In December, 2001, the United Nations Security Council authorized the creation and deployment of an International Security Assistance Force (ISAF) in Kabul, Afghanistan. The purpose of ISAF is to secure the city and the Bagram air base from Taliban and al Qaida elements and factional warlords, and to allow for the establishment and security of the Afghan Transitional Administration.
For almost two years, the ISAF mandate did not go beyond the boundaries of Kabul. According to General Norbert Van Heyst, such a deployment would require and extra 10,000 soldiers at least. That responsibility was to be given to the Afghan National Army. However, on October 13, 2003, the Security Council voted unanimously to expand the ISAF mission beyond Kabul. Shortly thereafter, Canadian Prime Minister Jean Chretien said that that Canadian peacekeepers (nearly half of the entire force) would not deploy outside Kabul.
On October 24, the German Bundestag voted to send German troops to Kunduz. Between 230 and 450 of the 1,600 German ISAF eventually be deployed. This marked the first time that ISAF soldiers operated outside of Kabul.
ISAF command rotated among different nations on a 6-month basis. However there was tremendous difficulty securing new lead nations. To solve the problem, command was turned over indefinitely to NATO on August 11, 2003. That day, Nicholas Burns, the U.S ambassador to NATO wrote in the Wall Street Journal that the mandate of ISAF should be expanded beyond the capital Kabul. One option he suggested would be for NATO to participate in U.S.-led "Provincial Reconstruction Teams" which were already active in trying to enforce security outside Kabul. NATO spokesman Mark Laity insisted, however, that NATO would stick to ISAF's Kabul-oriented mandate.
The history of ISAF command is as follows:
December 2001 to June 2002: under the command of Great Britain, led by Major General John McColl.
June 2002 to February 10, 2003: under the command of Turkey, led by Major General Hilmi Akin Zorlu.
February 10, 2003 to August 11, 2003: under the command of Germany and the Netherlands, led by Lieutenant General Norbert Van Hetst.
August 11, 2003 to present (indefinitely): under the command of NATO, led by NATO Lieutenant General Goetz Gliemeroth, with Canadian Army Major General Andrew Leslie as his deputy. (Canada) had been originally slated for August 11)). Canadian Lieutenant General Rick Hillier is scheduled to assume command of this NATO force in February, 2004.
In February 2002 South Korea sent a medical contingent of 99 soldiers.
In November, 2002 ISAF, consisting of 4,650 troops from over 20 countries, was led by Turkey. Around 1,200 German troops were serving in the force alongside 250 Dutch soldiers operating as part of a German-led battalion.
In March, 2003 ISAF was comprised of 4,700 troops from 28 countries.
On June 7, 2003 in Kabul, a taxi packed with explosives rammed a bus carrying German ISAF personnel, killing four soldiers and wounding 29 others; one Afghan bystander was killed and 10 Afghan bystanders were wounded. The 33 peacekeepers, after months on duty in Kabul, were en route to the Kabul International Airport for their flight home to Germany. At the time, Germans soldiers made up more than 40% of ISAF.
A study by Care International in the summer of 2003 reported that Kosovo had one peacekeeper to 48 people, East Timor one for every 86, while Afghanistan has just one for every 5,380 people.
August, 2003, ISAF consisted of 5,000 troops from more than 30 countries. About 90% of the force were contributed by NATO countries. 1,950 were Canadian, by far the largest single contingent. However, other reports suggested that about 2,000 German troops were involved. Romania had about 400 troops at the time.
As late as November, 2003, the entire ISAF force had three helicopters.

Julian de Guzman leads revitalized Canada on Hex quest: "We have no fear"
March 23, 20161:47PM EDT

Follow@ DanielSquizzato
Julian de Guzman could be getting ready for the biggest birthday party of his life.
The Canadian captain turns 35 on Friday, the same day Canada meet Mexico in a World Cup qualifier in front of an expected crowd of 50,000-plus at Vancouver's BC Place. He'll be honored prior to kickoff for becoming the national team's all-time leader in appearances (he's currently on 86 caps), but that's not the only birthday gift he hopes is in store.
"We know a win is very possible," de Guzman told reporters on Friday. "It'll be very difficult, but it's not impossible."
While it's not uncommon for underdog teams to speak highly of their own chances ahead of big contests, de Guzman attributes his confidence to a cultural shift brought into the program since the appointment of manager Benito Floro in mid-2013.
"He really believes in us," de Guzman says of Floro. "He has us believing in ourselves as well, and believing in him. As long as we hold onto that belief and that faith, we know we can make Russia [2018]."
It's ambitious talk for the former Toronto FC and FC Dallas midfielder, currently in his 14th year with the senior national team. But in what's surely his final World Cup qualifying cycle for Canada, de Guzman is prepared to give everything he has to help turn those dreams, at last, into reality.
"To be honest, being a part of the national team is one of the main reasons I'm still putting the boots on," he says. "It's a motivating factor; I want to help this country achieve something they haven't done in a long time."
De Guzman says he isn't looking ahead to his own potential involvement, if Canada were to somehow reach the 2018 World Cup. The immediate goal is reaching the Hexagonal round in CONCACAF qualifying, something Canada haven't done since 1997.
In that quest, the Canadian team has been bolstered by the recent additions of the likes of Tesho Akindele, Junior Hoilett and Steven Vitoria, as well as Scott Arfield, who is likely to make his debut for Canada in the upcoming qualifiers.
"It's just great to see guys finally commit to the national team," says de Guzman. "It's something Canada's been missing for such a long time."
De Guzman says the current team is one of the best Canadian squads, on paper, that he's ever been part of – but he's well aware that to make good on all the hype and positive momentum, the team must perform on the field when it matters most.
"The confidence coming into this camp, looking at the names we have on our side, we have no fear. It's a different feel versus the way it has been in the past," he says. "We're definitely confident to step up to this challenge ahead of us; not just comfortable but well prepared."
The team's actual results, though they've been trending upward in Floro's nearly three years at the helm, don't suggest that an upset win against Mexico is in the cards. But in de Guzman's mind, the influx of new talent and the team's buy-in to Floro's philosophies and tactics are coming together at exactly the right time to produce something special.
"We're playing against a top team, but we've been able to produce positive results at home," he says. "We're not just concerned about getting positive results, we want to win. That's our new mentality that we've been able to present with the national team.
"This is something we've been very hungry for and we can't wait to kick off."

Eurovision 2019: Rylan Clark hits back at claims Brexit could ruin UK's chances of winning
This year's edition of the Eurovision Song Contest continues in Israel tonight with the second batch of entries hopeful to go through to the final.
Rylan and Scott are posted in Tel Aviv to commentate on the semi-finals, and appeared on Good Morning Britain today to discuss whether there have been any changes to the atmosphere this year following the drama of Brexit negotiations.
Entertainment reporter Richard Arnold had flown over to Israel to chat to the commentators over breakfast.
Speaking via video link to Ben Shepherd and Susanna Reid in the ITV studio, he asked: "So is Eurovision more politically charged than ever?
"Let's put that question to our men on the ground every year here at Eurovision – Rylan and Scott Mills as well."
"To me, it's always just a music competition," Radio 1 DJ Scott replied. "So it doesn't feel any different for me.
"Does it feel any different from last year?" the presenter asked his co-host.
Considering his answer, Rylan noted there were some political notes to the contest, but he didn't think they were due to the developments with Brexit.
He shared: "No, I mean listen, sometimes the voting can get political.
"It's like, 'Oh you've given 12 points to your neighbour, of course you have.' But no, Eurovision is the one thing that personally I think, is not about that.
"It's just about the music," the former X Factor singer finished.
Susanna, 48, appeared more concerned with Richard's fashion choices for the occasion however.
Noting Rylan and Scott's uncannily similar outfits, she teased: "Richard you didn't get the tight black t-shirt memo?"
"I try not to wear dark colours too much when I'm abroad," the reporter laughed in response. "Because I get the sweat under boob patches!"
As the interview came to a close, fellow journalist and presenter Kate Garraway noted something very surprising.
Back in the studio, she said: "I don't think I've ever seen Richard so formal with Rylan. He shook his hand there!"
"It's because he's got a big job!" Susanna exclaimed, and Kate gave the Eurovision commentator a jokey warning.
"Rylan, don't muck it up," she said with a chuckle.
Also during today's programme, Laura Tobin accidentally swore live on air.
The weather reporter was forecasting from the Blackpool Tower on a harness and as the fear hit her she accidentally said "f**k".
Good Morning Britain airs weekdays at 6am on ITV and Eurovision 2019 semi-finals continue tonight at 8pm on BBC4.

The Supreme Court has directed the parties involved in a suit challenging the construction of a National Cathedral to file their legal arguments simultaneously within a week.
The court gave the direction last Tuesday after it had adopted the joint memorandum of issues filed by the legal team of the plaintiff, Mr James Kwabena Bomfeh, and the Attorney-General (A-G).
The memorandum is what would be adjudicated upon by the court.
Meanwhile, the court has granted a request by Mr Bomfeh's lawyers to amend their writ.
Counsel for Mr Bomfeh, Dr Aziz Bamba, informed the court about an application that he had filed seeking permission from the court to make changes to the writ.
A Deputy A-G, Mr Godfred Yeboah Dame, did not oppose the application for amendment.
The seven-member panel, presided over by Mr Justice Sophia Adinyera, fixed November 21, 2018 for hearing.
Other members of the panel are Mr Justice Jones Dotse, Mr Justice Anin Yeboah, Mr Justice Sule Gbadegbe, Mrs Justice Vida Akoto-Bamfo and Mr Justice A. A. Benin.
President Nana Akufo-Addo cut the sod for the construction of the National Cathedral on March 6, 2017, as part of events that marked Ghana's 60th independence anniversary.
Funding for the 5,000-seater edifice is to be sourced from individuals within the Christian community.
Plans by the government to demolish houses, including those housing judges, on the land around Ridge in Accra to make way for the construction of the cathedral generated a debate, with the public divided over the project.
In March last year, Mr Bomfeh, the acting General Secretary of the Convention People's Party (CPP), invoked the original jurisdiction of the Supreme Court, arguing that Ghana was a secular state and, therefore, it was wrong for the state to be "excessively entangled in any religion or religious practice".
He, therefore, wants the apex court to declare the building of the National Cathedral and state involvement in the Muslim pilgrimage to Mecca unconstitutional.
He is seeking "a declaration that the decision of the Government of Ghana to purposely endorse, assist, aid, partly sponsor, and/or support the construction of a national cathedral near the State House of Ghana, for Christian interdenominational church services amounts to an excessive entanglement of the Republic of Ghana in religion and therefore unconstitutional''.
In September 2018, Mr Bomfeh filed an application for interlocutory injunction seeking to restrain any activity towards the construction of the cathedral, including the demolition of residences of judges.

\section{introduction}

Perturbative quantum chromodynamics (pQCD) calculations are essential to describe processes with large momentum transfer. The double charmonium production processes, $e^{+}+e^{-}\rightarrow J/ \psi \;(\psi') + \chi_{cJ}$ with $(J=0,1,2)$, play an important role for understanding the production and hadronization properties of the heavy quarkonium. In addition to being a demonstration of the non-relativistic QCD (NRQCD) factorization \cite{nrqcd}, such kind of charmonium production also provides a good opportunity to learn pQCD color-singlet mechanism~\cite{npb172425}.

In the literature, these processes have been studied within the pQCD factorization up to next-to-leading order (NLO), cf. Refs.\cite{br:2005lo,liu:2003lo1,liu:2003lo2,Zh:2008nlo,W:2011nlo,Dong:2011nlo}. Their polarized cross sections up to NLO can be written as
\begin{eqnarray}
\sigma^{J}_{\lambda_1,\lambda_2} &=& \sigma^J_{\lambda_1,\lambda_2}\left|_{\rm LO}\right. + \sigma^J_{\lambda_1,\lambda_2}\left|_{\rm NLO}\right. \nonumber\\
&=& A^J_{\lambda_1,\lambda_2}\; \alpha^{2}_{s}(\mu_R)\; \left\{1+{\alpha_s(\mu_R) \over \pi} B^J_{\lambda_1,\lambda_2}(\mu_R) \right\} , \label{pol:cross:section}
\end{eqnarray}
where $\lambda_1$ and $\lambda_2$ stand for the helicities of the outgoing $J/\psi$ and $\chi_{cJ}$. The tree-level coefficients
\begin{eqnarray}
A^J_{\lambda_1,\lambda_2} &=& {32\pi e_c^2 \alpha^2 C_F^2 \over 3 s^2 m_c^6} \left({|{\bf P}|\over \sqrt{s}}\right) |R_{J/\psi}(0)|^2 |R'_{\chi_{cJ}}(0)|^2 \nonumber\\
&& \times\; r^{(1+|\lambda_1+\lambda_2|)} \left| c^J_{\lambda_1,\lambda_2}(r) \right|^2 ,
\end{eqnarray}
where the charm quark electric charge $e_c={2/3}$ and the color factor $C_F$= $4/3$. The dimensionless parameter $r={4m^{2}_{c} / s}$, and $|{\bf P}|=\lambda^{1\over 2}(s,M^2_{J/\psi},M^2_{\chi_{cJ}}) / (2\sqrt{s})$, where
\begin{displaymath}
\lambda(x,y,z)=x^2+y^2+z^2-2xy-2yz-2zx .
\end{displaymath}
The parameters $|R_{J/\psi}(0)|$ and $|R'_{\chi_{cJ}}(0)|$ are the radial wavefunction at the origin and the first derivative of the radial wavefunction at the origin for $J/\psi$ and $\chi_{cJ}$, respectively. The LO coefficients $c^J_{\lambda_1,\lambda_2}$ and the NLO coefficients $B^J_{\lambda_1,\lambda_2}(\mu_R)$ are put in the Appendix. The parameter $\mu_R$ stands for the renormalization scale.

For calculating all the polarized and the unpolarized cross sections of the processes $e^{+}+e^{-}\rightarrow J/ \psi \;(\psi') + \chi_{cJ}$, one needs to introduce the renormalization scale $\mu_R$. In the literature, it is usually taken as the typical momentum flow of the process ($Q$), e.g. $Q=2m_c$ or $\sqrt{s}/2$ or $\sqrt{s}$, respectively. However which one can result in the right theoretical estimation is not clear. As for conventional scale setting, the renormalization scale is fixed once it has been set to be $Q$; for convenience, we call it the initial renormalization scale $\mu_R^{\rm init}$. That is, under conventional scale setting, one always sets $\mu_R\equiv\mu_R^{\rm init}=Q$. It has been observed that under such scale setting, one usually obtains sizable renormalization scale dependent estimation \cite{br:2005lo,liu:2003lo1,liu:2003lo2,Zh:2008nlo,W:2011nlo,Dong:2011nlo}, which could be up to $40\%-50\%$ for taking $\mu_R$ to be the above mentioned three typical scales, and up to $10\%-20\%$ by varying $\mu_R$ within the region of $[Q/2,2Q]$ for a specific $Q$. Thus, the renormalization scale uncertainty usually provides a large systematic error under the conventional scale setting. Especially, the arbitrary choice of $[Q/2,2Q]$ could be misleading in certain cases. For example, Ref.\cite{Q6} argues that after including the first and second order corrections to the deep inelastic sum rules which are due to heavy flavor contributions, the renormalization scale $\mu_{R}$ should be taken as $\mu_R \sim 6.5 \,m$, if taking the typical scale $Q$ to be the corresponding heavy quark mass $m$.

Recently, it has been pointed out that the principle of maximum conformality (PMC) provides a possible solution for eliminating such renormalization scale ambiguity~\cite{pmc1,pmc2,pmc3,pmc4,pmc5,pmc6,pmc7}. PMC provides the underlying principle for the BLM mechanism~\cite{blm}, a recent review on PMC can be found in Ref.\cite{pmc8}.

The main idea of PMC lies in that one can first finish the renormalization procedure for any pQCD process by using an initial value for the renormalization scale ($\mu_R^{\rm init}$), and then set the effective or optimal PMC scale for the process. The PMC scale is generally different from $\mu_R^{\rm init}$, which is formed by absorbing all non-conformal terms that rightly governs the running behavior of the coupling via the renormalization group equation into the coupling constant~\cite{pmc2}. In different to conventional scale setting, one can choose any arbitrary value to be $\mu^{\rm init}_R$, but the optimal PMC scale and the resulting finite-order PMC prediction are both to high accuracy independent of such arbitrariness, consistent with the renormalization group invariance. The PMC satisfies all self-consistency conditions for setting the renormalization scale~\cite{pmc5}. After proper procedures, all non-conformal $\{\beta_i\}$-terms in the perturbative expansion are summed into the running coupling so that the remaining terms in the perturbative series are identical to that of a conformal theory. The QCD predictions from PMC are then independent of renormalization scheme, inversely, such scheme independence can be adopted to derive commensurate scale relations among different observables~\cite{csr}. Moreover, after PMC scale setting, the divergent ``renormalon" series $(n!\;\beta_i^{n}\alpha_s^n)$ does not appear in the conformal series and the convergence of the pQCD series can be greatly improved in principle. For example, such merits have been shown by a next-to-next-to-leading order (NNLO) PMC analysis of the top-quark pair production at the hadronic colliders~\cite{pmc3,pmc4}. As the main purpose of the present paper, we shall show that even at the NLO level, the pQCD prediction after PMC scale setting can also have such good features, thus our understanding of $e^+ + e^- \rightarrow J/\psi + \chi_{cJ}$ can be greatly improved.

The remaining parts of the paper are organized as follows. In Sec.II, we give the polarized and unpolarized cross sections for the double charmonium production under PMC scale setting. Numerical results and discussions are presented in Sec.III. The final section is reserved for a summary.

\section{polarized and unpolarized cross sections}

To set the PMC scales for high-energy processes, one needs to decompose the perturbative coefficients at each $\alpha_s$ order into $\{\beta_i\}$-dependent and independent parts respectively. For the double charmonium production at the NLO level, we need to decompose the NLO coefficient $B^J_{\lambda_1,\lambda_2}(\mu^{\rm init}_R)$ into $\beta_0$-dependent part (non-conformal part) and $\beta_0$-independent part (conformal part), i.e.
\begin{equation}
B^J_{\lambda_1,\lambda_2}(\mu^{\rm init}_R) = B^{J(\beta)}_{\lambda_1,\lambda_2}(\mu^{\rm init}_R) \beta_0 + B^{J(con)}_{\lambda_1,\lambda_2}(\mu^{\rm init}_R) ,
\end{equation}
where the non-conformal $B^{J(\beta)}_{\lambda_1,\lambda_2}(\mu^{\rm init}_R)$ and the conformal $B^{J(con)}_{\lambda_1,\lambda_2}(\mu^{\rm init}_R)$ can be found in the Appendix. Then, following the standard procedure of PMC, the polarized cross section (\ref{pol:cross:section}) can be rewritten as,
\begin{widetext}
\begin{eqnarray}
\sigma^{J}_{\lambda_1,\lambda_2} &=& A^J_{\lambda_1,\lambda_2} \;\alpha^{2}_{s} \left(\mu^{\rm PMC}_{R,(\lambda_1,\lambda_2)}\right)\times \left \{1+{\alpha_s \left(\mu^{\rm PMC}_{R,(\lambda_1,\lambda_2)}\right) \over \pi} B^{J(con)}_{\lambda_1,\lambda_2}\left(\mu^{\rm init}_R\right) \right\}
\end{eqnarray}
\end{widetext}
with the PMC scale
\begin{equation}\label{pmcscale}
\mu^{\rm PMC}_{R,(\lambda_1,\lambda_2)}=\mu^{\rm init}_R \exp{\left( {-B^{J(\beta)}_{\lambda_1,\lambda_2}\left(\mu^{\rm init}_R\right)} \right)} .
\end{equation}
It shows that the PMC scales are determined by the non-conformal terms which govern the dominant behavior of the running coupling constant. At present, because the non-conformal terms $B^{J(\beta)}_{\lambda_1,\lambda_2}(\mu^{\rm init}_R)$ are different for $J=0,1,2$, the PMC scales, and hence the theoretical estimations, for these cross sections are also different. This is one of the important features of PMC scale setting.

Similarly, the NLO coefficients $B^J_{t}(\mu^{\rm init}_R)$ of the unpolarized/total cross sections can also be decomposed into the non-conformal part $B^{J(\beta)}_{t}(\mu^{\rm init}_R)$ and the conformal part $B^{J(con)}_{t}(\mu^{\rm init}_R)$. After PMC scale setting, the total cross section
\begin{eqnarray}
\sigma^J_{t} &=& \sigma^J_{t}(\mu^{\rm init}_R) \left|_{\rm LO}\right. \times \nonumber\\
&& \left\{1+{\alpha_s(\mu^{\rm init}_R)\over\pi}\left( B^{J(\beta)}_{t}(\mu^{\rm init}_R) \beta_0 + B^{J(con)}_{t}(\mu^{\rm init}_R) \right)\right\} \nonumber
\end{eqnarray}
reduces to
\begin{equation}\label{pmctotal}
\sigma^J_{t}=\sigma^J_{t}(\mu^{\rm PMC}_{R;t,J})\left|_{\rm LO}\right. \left \{1+{\alpha_s(\mu^{\rm PMC}_{R;t,J}) \over\pi} B^{J(con)}_{t}\left(\mu^{\rm init}_R\right) \right\}
\end{equation}
with the PMC scale,
\begin{equation}
\mu^{\rm PMC}_{R;t,J}=\mu^{\rm init}_R \exp{\left(-B^{J(\beta)}_{t}(\mu^{\rm init}_R)\right)} .
\end{equation}
It is noted that the initial scale dependent logarithmic terms in $B^{J(con)}_{\lambda_1,\lambda_2} \left(\mu^{\rm init}_R\right)$ and $B^{J(con)}_{t}\left(\mu^{\rm init}_R\right)$ should be absorbed into the coupling constant simultaneously with the non-conformal terms via the renormalization group equation of the coupling constant, so after applying PMC scale setting, $B^{J(con)}_{\lambda_1,\lambda_2}$ and $B^{J(con)}_{t}$ are still at the initial scale $\mu^{\rm init}_R$. As for the functions of the total cross sections (\ref{pmctotal}), we have
\begin{widetext}
\begin{eqnarray}
\sigma^0_{t}\left|_{\rm LO}\right. &=& \sigma^0_{0,0} \left|_{\rm LO}\right. + 2 \sigma^0_{1,0}\left|_{\rm LO}\right., \\
B^{0(con)}_{t} &=& \frac{1} {\sigma^0_{t} \left|_{\rm LO}\right.} \left(B^{0(con)}_{0,0} \sigma^0_{0,0}\left|_{\rm LO}\right. +2B^{0(con)}_{1,0} \sigma^0_{1,0}\left|_{\rm LO}\right. \right), \\
B^{0(\beta)}_{t} &=& \frac{1}{\sigma^0_{t}\left|_{\rm LO}\right.} \left(B^{0(\beta)}_{0,0} \sigma^0_{0,0}\left|_{\rm LO}\right. +2B^{0(\beta)}_{1,0} \sigma^0_{1,0}\left|_{\rm LO}\right. \right)
\end{eqnarray}
for $J=0$;
\begin{eqnarray}
\sigma^1_{t}\left|_{\rm LO}\right. &=&2 \left(\sigma^1_{1,0}\left|_{\rm LO}\right. +\sigma^1_{0,1}\left|_{\rm LO}\right. + \sigma^1_{1,1}\left|_{\rm LO}\right. \right) ,

for $J=2$, respectively. Here, for convenience, we have omitted the initial scale $\left(\mu^{\rm init}_R\right)$ dependence to the coefficients $B^{J(con)}_{t}$ and the PMC scale $\left(\mu^{\rm PMC}_{R;t,J}\right)$ dependence in the LO cross sections.
\end{widetext}

The summed up non-conformal functions $B^{J(\beta)}_{t}(\mu^{\rm init}_R)$ are usually different from their polarized terms $B^{J(\beta)}_{\lambda_1,\lambda_2}(\mu^{\rm init}_R)$, then the PMC scales for the total cross sections are generally different from the PMC scales for the polarized cross sections. Furthermore, because the non-conformal terms $B^{J(\beta)}_{t}(\mu^{\rm init}_R)$ are different for $J=0,1,2$, the PMC scales of these total cross sections are also different. Thus, for the considered processes, we have to introduce several PMC scales for the polarized and the unpolarized cross sections. The physical picture for the introducing of different PMC scales is clear, all PMC scales are determined by those known $\{\beta_i\}$-terms that rightly determine the running behavior of the strong coupling constant in each case.

It is noted that these PMC scales only formally depend on the choice of the initial renormalization scale, but as will be shown later, all these PMC scales are almost independent of the initial choice of renormalization scale, and then the renormalization scale dependence can be greatly suppressed (or even eliminated in comparison to the errors caused by other uncertainty sources as $m_c$, $|R_{J/\psi}(0)|$, $|R'_{\chi_{cJ}}(0)|$ and etc.). As a consistent cross-check of PMC estimation, it is helpful to show whether after PMC scale setting, by summing up all the polarized cross section, one can still get the same result as that of the directly calculated unpolarized cross section. This, inversely, can also be used as a criteria of whether the complex higher-order calculations are right or not.

At the NLO level, it is noted that the coefficients proportional to $n_f$ or $\beta_0$ are the same, so one can practically obtain $\mu^{\rm PMC}_{R} = \mu^{\rm BLM}_{R}$. But there are advantages for using PMC other than BLM:
\begin{itemize}
\item The PMC provides the underling principle for BLM, which clearly shows how the $n_f$-terms are eliminated. The PMC can be extended to any perturbative order in a self-consistent way.
\item That is, to set the optimized scale, it is not simply to set the coefficient before $n_f$ to zero but to eliminate $n_f$ in a combined form as $\beta_0$ or other $\{\beta_i\}$-functions that rightly governs the running behavior of the coupling constant. Otherwise, one may not get the correct conformal term for estimating the physical observable, especially in some specific cases when the conformal and non-conformal terms have no connection~\cite{pmc5}.
\item By using PMC scale setting, one can conveniently show how the pQCD convergence can be improved in principle and how the renormalization scale dependence can be greatly suppressed or eliminated even at the NLO level.
\end{itemize}

\section{numerical results and discussions}

\subsection{Input parameters}

To do numerical calculation, we set the collision energy $\sqrt{s}=10.6$ GeV, the charm quark mass $m_c=1.5$ GeV \footnote{We adopt the so called 1S-mass for $m_c$ \cite{1Smass1,1Smass2}, i.e. half of the $J/\Psi$-mass for charm quark, which is consistent with the bound-state parameters under the potential-model calculations~\cite{wforigin1,wforigin2}. } and $\alpha(\sqrt{s})=1/130.9$ \cite{fine:130fine}. Using the two-loop $\alpha_s$ running with $\alpha(M_{Z})=0.1184$~\cite{pdg}, we obtain $\Lambda^{(n_f=3)}_{\rm QCD}=0.386$ GeV, $\Lambda^{(n_f=4)}_{\rm QCD}=0.332$ GeV, and $\Lambda^{(n_f=5)}_{\rm QCD}=0.231$ GeV. Based on the experimental values for the leptonic width of $J/\psi$ and $\psi(2S)$ and the width of $\chi_{c2}$ to two photons, we can inversely determine the radial wavefunction $|R_{ns}(0)|$ at the origin and the first derivative of the radial wavefunction at the origin $|R^{'}_{np}(0)|$ through the NLO formulas~\cite{pdg}
\begin{equation}
\Gamma_{\psi(ns)\rightarrow e^+e^-} = {4\alpha^2\over 9m^2_c}\left(1-{16\alpha_s(2m_c) \over 3\pi}\right)|R_{ns}(0)|^2 \label{wave1}
\end{equation}
and
\begin{equation}
\Gamma_{\chi(np)\rightarrow \gamma\gamma} = {64\alpha^{2}\over 45m^{4}_{c}}\left(1-{16\alpha_{s}(2m_c) \over 3\pi}\right)|R^{'}_{np}(0)|^{2}. \label{wave2}
\end{equation}
To be consistent with the present NLO analysis of quarkonium pair production, we need a NLO determination of $|R_{ns}(0)|$ and $|R^{'}_{np}(0)|$. To set the PMC scales for those decay widths, one needs to finish the NNLO calculation for these processes, which however are not available at present due to its complexity. For simplicity, we set its scale as the one usually suggested in the literature, i.e. $\mu_R=2m_c$, and only provide a rough estimation on different scale choices. For experimental values of these decay widths, we adopt those from the Particle Data Group~\cite{pdg}: $\Gamma_{J/\psi\rightarrow e^+e^-} =(5.55\pm0.16)$ keV, $\Gamma_{\psi'\rightarrow e^+e^-} =(2.37\pm0.04)$ keV and $\Gamma_{\chi_{c_2}\rightarrow \gamma\gamma}=(0.514\pm0.062)$ keV. Then, as a combined error being the squared average of the experimental errors on the decay widths and the theoretical errors caused by varying the scale within the conventional region of $[m_c,4m_c]$, we obtain:
\begin{eqnarray}
|R_{J/\psi}(0)|^{2} &=& \left(0.855^{+0.044}_{-0.051}\right) \;{\rm GeV}^{3} , \label{wfval1}\\
|R_{\psi^{'}}(0)|^{2} &=& \left(0.365^{-0.017}_{-0.020}\right) \;{\rm GeV}^{3} , \label{wfval2} \\
|R^{'}_{\chi_{cJ}}(0)|^{2} &=& \left(0.056^{+0.007}_{-0.007}\right) \;{\rm GeV}^{5} , \label{wfval3}
\end{eqnarray}
where we have neglected the spin-effects in both the same level $S$-wave and $P$-wave states, and treat all $1P$-wave states have the same $|R^{'}_{1p}(0)|=|R^{'}_{\chi_{cJ}}(0)|$. At present, in order to provide a relatively reliable estimation of the scale error, following the idea of PMC, we first transform  Eqs.(\ref{wave1},\ref{wave2}) into general renormalization scale dependent forms by including the dominant log-terms, which have been eliminated by directly setting the renormalization scale to be the typical momentum transfer $(2m_c)$~\cite{wangsq}. That is, before analyzing the scale error, Eqs.(\ref{wave1},\ref{wave2}) are rewritten by using conventional running behavior of the coupling constant as
\begin{eqnarray}
&&\Gamma_{\psi(ns)\rightarrow e^+e^-} = {4\alpha^2\over 9m^2_c}|R_{ns}(0)|^2 \times\nonumber\\
&&\quad \left[1-{16\alpha_s(\mu_R) \over 3\pi}\left(1+\beta_{0}\ln\left(\frac{\mu_R^2}{\mu_{R,0}^2}\right) \frac{\alpha_s(\mu_R)}{4\pi}\right)\right] ,\\
&&\Gamma_{\chi(np)\rightarrow \gamma\gamma} = {64\alpha^{2}\over 45m^{4}_{c}}|R^{'}_{np}(0)|^{2}\times \nonumber\\
&&\quad \left[1-{16\alpha_{s}(\mu_R) \over 3\pi}\left(1+\beta_{0}\ln\left(\frac{\mu_R^2}{\mu_{R,0}^2} \right) \frac{\alpha_s(\mu_R)}{4\pi}\right)\right] ,
\end{eqnarray}
where $\beta_0=11-2n_f/3$ and $\mu_{R,0}=2m_c$. Some subtle points need to be mentioned: I) This scale error analysis follows the idea of PMC but is an approximation because of lacking strict NNLO $\{\beta_i\}$-terms to determine its PMC scales; II) Only part of the two-loop correction that partly determines the running behavior of coupling constant has been considered, since it only involves the log-term $\ln\left({\mu_R^2}/{\mu_{R,0}^2} \right)$ dependent $\beta$-functions. Even though such log term is at the one-order higher, it is necessary and can largely compensate the scale changes at the NLO level, otherwise, one will obtain abnormally large scale errors. III) Since the choice of typical momentum flow is not unique, different choice of it may lead to extra scale uncertainties. IV) In some sense, the present idea of including the dominant scale running effect determined by the renormalization group equation into the scale error analysis is consistent with the idea of the principle of minimum sensitivity (PMS)~\cite{pms}, in which the renormalization scale is so set as to minimize the sensitivity of the estimation to the scale variation. That is, we observe that the scale choice of $\mu_R=2m_c$ corresponds to a steady point for those decay widths. This also agrees with the observation of Ref.\cite{pmc8}, i.e. even though the PMS does not satisfy the reflexivity, symmetry and transitivity properties of the renormalization group as PMC does, the PMS is consistent with PMC at least at the NLO level in which its NLO coefficients are also free from $\beta$-terms.

These values for the wavefunction parameters are consistent with those of Ref.\cite{W:2011nlo} and those derived from the potential models such as Refs.~\cite{wforigin1,wforigin2,wforigin3,wforigin4} within reasonable errors. At present, the wavefunction parameters $|R_{ns}(0)|$ and $|R^{'}_{np}(0)|$ appear in the amplitude as a linear factor, so the uncertainties for the charmonium production channels can be figured out straightforwardly, thus, throughout the paper if not specially stated, we shall fix their values to be their central values \footnote{A better determination of those parameters, such as the consideration of quark mass effect, relativistic effect, higher order effect and etc., shall be helpful for deriving an accurate estimation. Such an analysis is out of the range of present paper.}.

\end{figure}

We present the total cross sections before and after PMC scale setting in Table \ref{scaleun}, where three typical momentum flows are adopted as the initial scale $\mu^{\rm init}_{R}$. Under conventional scale setting, $\mu_R\equiv \mu^{\rm init}_{R}$, the total cross sections are quite sensitive to the choice of renormalization scale. For example, by varying $\mu^{\rm init}_R$ from $2m_c$ to $\sqrt{s}/2$, total cross sections for the cases of $\chi_{c0}$, $\chi_{c1}$ and $\chi_{c2}$ production are changed by about $26\%$, $16\%$ and $8\%$ respectively. This observation agrees with previous estimations obtained in the literature~\cite{br:2005lo,liu:2003lo1,liu:2003lo2,Zh:2008nlo,W:2011nlo,Dong:2011nlo}. Then, the scale uncertainty always constitutes an important error source for the conventional estimation. We do not know which scale could be the answer unless by comparing with data, which however greatly suppresses the predictive power of pQCD. On the other hand, after PMC scale setting, we observe that the total cross sections for $\chi_{c0}$, $\chi_{c1}$ and $\chi_{c2}$ production remain almost unchanged by varying $\mu^{\rm init}_{R}$ to be disparate ones as $2{\rm m_{c}}$, ${\sqrt{s}/2}$ and $\sqrt{s}$. More explicitly, we present the total cross section versus $\mu^{\rm init}_{R}$ in Fig.(\ref{Plot:sqrst:a}). It shows that, the total cross sections are almost flat versus the initial renormalization scale, then the renormalization scale ambiguity is eliminated even at the NLO level. After PMC scale setting, we have resummed the non-conformal $\{\beta_0\}$-terms known at the NLO level into the coupling constant, generally, the LO cross sections will be significantly increased, while the NLO corrections are suppressed to a certain degree. Then, the perturbative convergence can be improved, in principle. The large $\beta_0$-approximation in this sense is consistent with our present treatment, in which all $\beta_0$-terms have been summed up, e.g. for the quarkonium electromagnetic annihilation decays~\cite{chen}. It is noted that the PMC scale setting can be conveniently extended up to any perturbative order, and any other type of $\beta$-terms can also be summed up in a consistent way.

A comparison of our estimations with the experimental results are shown in Table \ref{cross-m} and \ref{cross-n}, where as a comparison, we also list the results of Refs.\cite{W:2011nlo,Dong:2011nlo}. The errors for our present estimations are listed in Table \ref{cross-m}, which are caused by varying $m_c\in [1.40\;{\rm GeV}, 1.60\;{\rm GeV}]$ and by considering the uncertainties of the wavefunction parameters $|R_{ns}(0)|$ and $|R^{'}_{np}(0)|$ determined by Eqs.(\ref{wfval1},\ref{wfval2},\ref{wfval3}). Our estimation for the total cross section of $J/\psi+\chi_{c0}$ production is consistent with the experimental result, but the $\psi'+\chi_{c0}$ production cross section is still smaller than the central value of the data. Since the data is still with large error, a future more accurate measurement shall be helpful to clarify this puzzle. As a final remark, there is residual scale dependence due to unknown higher order $\{\beta_i\}$-terms, which however is highly suppressed~\cite{pmc1,pmc2,pmc3,pmc4,pmc5}.

\end{figure*}

In addition to the cases of the total cross sections, it is also interesting to show how PMC scale setting affects the polarized cross sections. We take $e^{+}+e^{-}\rightarrow J/ \psi + \chi_{cJ}$ as an explicit example. For each polarized process, the coefficients for the conformal or the non-conformal terms are different due to the enhancement or cancelation among different polarizations, then it is reasonable that the effective momentum flows of them are different. So, in principle, we should introduce different PMC scales for each polarized process.

More explicitly, we put the PMC scales for the polarized cross section versus the initial renormalization scale $\mu^{\rm init}_R$ in Fig.(\ref{Plot:mu:pmcscale}), where the PMC scales for $J=0,1,2$ are presented. All PMC scales for the polarized cross sections are almost independent of the initial renormalization scale, which are similar to the cases of total cross sections. Then, the scale uncertainty are also eliminated for the polarized cross sections at the NLO level. This also shows that our present calculation for both the polarized and unpolarized cross sections are consistent with each other. Fig.(\ref{Plot:mu:pmcscale}) shows
\begin{itemize}
\item For $e^{+}+e^{-}\rightarrow J/ \psi + \chi_{c0}$ process, we need to introduce two different PMC scales for $(\lambda_1,\lambda_2)=(0,0)$ and $(1,0)$, respectively. The contribution from the helicity channel $(1,0)$ is about $2$ times larger than that of the $(0,0)$ channel.
\item For $e^{+}+e^{-}\rightarrow J/ \psi + \chi_{c1}$ process, we need to introduce three PMC scales. The PMC scales for $(\lambda_1,\lambda_2)=(0,1)$ and $(1,1)$ are equal to each other due to the same non-conformal terms $B^{1(\beta)}_{0,1}=B^{1(\beta)}_{1,1}$, so we only have two different PMC scales. The helicity channel $(0,1)$ provides the dominant contribution for this process.
\item For $e^{+}+e^{-}\rightarrow J/ \psi + \chi_{c2}$ process, we need to introduce five PMC scales corresponding to five helicity channels. The PMC scales for $(\lambda_1,\lambda_2)=(0,1)$ and $(1,1)$ are the same due to the same non-conformal terms $B^{2(\beta)}_{0,1}=B^{2(\beta)}_{1,1}$, while other PMC scales are different, so we have four different PMC scales. The contribution from the helicity channels $(0,0)$ and $(1,0)$ are dominant over others.

Because of the exponential suppression to the PMC scale as shown by Eq.(\ref{pmcscale}), the LO cross section for each polarized cross section shall be increased to a certain degree, which are shown clearly in Tables \ref{scaleun0}, \ref{scaleun1} and \ref{scaleun2}. Defining a parameter $C$, being the ratio of the cross section at NLO level to that at LO level, we find that the parameter $C$ are $0.73$ and $0.82$ for $(\lambda_1,\lambda_2)=(0,0)$ and $(1,0)$ channels of $e^{+}+e^{-}\rightarrow J/ \psi + \chi_{c0}$ under the conventional scale setting; which however changes down to $0.08$ and $0.49$ after PMC scale setting. For $e^{+}+e^{-}\rightarrow J/ \psi + \chi_{c1,2}$, the conditions are similar. This shows that the pQCD series become more convergent after PMC scale setting.

\section{summary}

We have applied PMC scale setting to study the polarized and the unpolarized cross sections of $e^{+}+e^{-}\rightarrow J/ \psi + \chi_{cJ}(J=0,1,2)$ up to NLO level. After PMC scale setting, we find that the final results are scale- and scheme- independent and the pQCD series becomes more convergent for both the polarized and the unpolarized cross sections. So we gain a more accurate pQCD estimation than those in the literature. More explicitly,
\begin{itemize}
\item After PMC scale setting, we obtain the following total cross sections
    \begin{eqnarray}
\sigma(J/\psi+\chi_{c0}) &=& 12.25^{+3.70}_{-3.13}\; {\rm fb},\;\nonumber\\
\sigma(J/\psi+\chi_{c1}) &=& 1.00^{+0.41}_{-0.32}\; {\rm fb},\;\nonumber\\
\sigma(J/\psi+\chi_{c2}) &=& 1.58^{+0.49}_{-0.43}\; {\rm fb}\nonumber
    \end{eqnarray}
    and
    \begin{eqnarray}
\sigma(\psi'+\chi_{c0})  &=& 5.23^{+1.56}_{-1.32}\; {\rm fb},\;\nonumber\\
\sigma(\psi'+\chi_{c1})  &=& 0.43^{+0.17}_{-0.14}\; {\rm fb},\;\nonumber\\
\sigma(\psi'+\chi_{c2})  &=& 0.67^{+0.22}_{-0.18}\; {\rm fb},\nonumber
   \end{eqnarray}
   where the errors are caused by taking the charm quark mass $m_c\in [1.40\;{\rm GeV}, 1.60\;{\rm GeV}]$ and the uncertainties of the wavefunction parameters $|R_{ns}(0)|$ and $|R^{'}_{np}(0)|$ determined by Eqs.(\ref{wfval1},\ref{wfval2},\ref{wfval3}). Our estimation for the total cross section of $J/\psi+\chi_{c0}$ production is consistent with the experimental result, but the $\psi'+\chi_{c0}$ production cross section is still far less than the central value of the $B$-factory data~\cite{be:2004xa,be:2004data,ba:2005data}. Since the data is still with large error, a future more accurate measurement shall be helpful to clarify this puzzle.

\item A comparison of Tables \ref{cross-m}, \ref{scaleun0}, \ref{scaleun1} and \ref{scaleun2} shows that $e^{+}+e^{-}\to J/ \psi (\psi') + \chi_{cJ}$ processes are dominated by $J=0$ channel, which have been measured at the $B$ factories. In contrast, the contribution of the $e^{+}+e^{-}\rightarrow J/ \psi (\psi') + \chi_{c1,c2}$ channels for this process seem to be rather modest even after PMC scale setting, which are about one order lower than that of $\chi_{c0}$ production case. The future super $B$ factory, with much higher luminosity, may eventually observe these polarization patterns.

\item Under conventional scale setting, the NLO contribution for all the channels are not small. After PMC scale setting, the pQCD convergence are greatly improved for most of the polarized and unpolarized channels. Thus the unknown NNLO corrections for those channels will not changes our present estimations much, since the contributions from those unknown NNLO $\beta$-terms shall be exponentially suppressed to the present PMC scales~\cite{pmc1,pmc2,pmc3}, which inversely guarantees the unknown conformal terms also provide less important contributions than that of the NLO conformal term. There are also cases when the pQCD convergence cannot be improved even after applying the PMC scale setting. For those cases, we really need a NNLO calculation to make the pQCD estimation more reliable, but which will also not heavily change our present estimations and conclusions. This is similar to the case of top-pair production at the hadronic colliders, where we have found that after the PMC scale setting, not only the scale dependence can be eliminated but also the pQCD convergence can be greatly improved only after finishing a NNLO calculation~\cite{pmc1,pmc3,pmc4}.

\item As a cross check, by taking all the same input parameters, we exactly obtain the results listed in Ref.\cite{Dong:2011nlo}. It is found that after PMC scale setting, even though we have introduced different PMC scales for different type of cross sections caused by the different non-conformal terms, by summing up all the polarized cross sections, we can get the same result as that of the directly calculated unpolarized cross section for the case of $J=0$ and $J=1$. This shows that our PMC procedure is self-consistent. However, there is slight difference for the case of $J=2$. This shows that the expression for the coefficient $B^{2(con)}_{0,0}$ listed in Ref.\cite{Dong:2011nlo} could have some typos for the conformal terms.

\item It is found that after PMC scale setting, for the polarized cross sections $\sigma^{1}_{1,0}$ (negative even before PMC scale setting) and $\sigma^{2}_{0,0}$, we obtain the ``incorrect" negative cross section. Similar to the QCD pomeron case, this could be the problem of the unphysical $\overline{\rm MS}$-scheme itself~\cite{pomeron1,pomeron2}. It has already been pointed that there is also the same ``incorrect" sign for the NLO highest eigenvalue of the BFKL equation under the $\overline{\mbox{MS}}$-scheme~\cite{pomq1,pomq2}. In Ref.\cite{pomeron1}, it has been shown that the reliability of QCD predictions for the intercept of the BFKL pomeron at NLO when evaluated using the physical schemes, such as the momentum space subtraction (MOM) scheme \cite{mom1,mom2,mom3}, can be significantly improved.

    The ``incorrect" sign for $\sigma^{1}_{1,0}$ and $\sigma^{2}_{0,0}$ under $\overline{\rm MS}$ scheme may show that those unknown non-conformal terms from the NNLO or higher orders should have sizable contributions to the LO PMC scale and can not be safely neglected. In fact, the large $K$ factor for these two polarized cross sections shows their pQCD convergence are terrible. It is found that when we transforming the cross sections from the $\overline{\rm MS}$ schemes to the MOM scheme, such ``incorrect" sign disappears. A detailed discussion on this point shall be presented elsewhere~\cite{prepare}.

\item As a final remark: $e^{+}+e^{-}\to J/ \psi (\psi') + \chi_{cJ}$ processes provide another good example for eliminating the renormalization scale ambiguity by using the PMC. Thus, after applying PMC scale setting, it will not only increase the precision of QCD tests, but also it will increase the sensitivity of the collider experiments to new physics beyond the standard model.

\section*{Appendix: coefficients for the LO and NLO terms}

The expressions for the LO coefficients $c^J_{\lambda_1,\lambda_2}$ and the NLO coefficients $B^J_{\lambda_1,\lambda_2}(\mu_R)$ can be found in Ref.\cite{Dong:2011nlo}. Here, we correct some more typos in the non-conformal $\{\beta_0\}$-terms that are listed in Ref.\cite{Dong:2011nlo} by using explicit relations among the same polarization combination $(\lambda_1,\lambda_2)$ with different $J$ \footnote{Those relations are confirmed through private communications with the authors of Ref.\cite{Dong:2011nlo}.}. For convenience, we put all the LO coefficients $c^J_{\lambda_1,\lambda_2}(r)$ in the following
\begin{eqnarray}
c^0_{0,0}(r) &=& -1-10r+12r^2, \nonumber\\
c^0_{1,0}(r) &=& -9+14r, \nonumber\\
c^1_{0,1}(r) &=& \sqrt{6}(2-7 r), \nonumber\\
c^1_{1,0}(r) &=& -\sqrt{6}r, \nonumber\\
c^1_{1,1}(r) &=& 2\sqrt{6}(1-3r), \nonumber\\
c^2_{0,0}(r) &=& \sqrt{2}(-1+2r+12r^2), \nonumber\\
c^2_{0,1}(r) &=& \sqrt{6}(-1+5r), \nonumber\\
c^2_{1,0}(r) &=& \sqrt{2}(11r-3), \nonumber\\
c^2_{1,1}(r) &=& 2\sqrt{6}(1-3r), \nonumber\\
c^2_{1,2}(r) &=& -2\sqrt{3}. \nonumber
\end{eqnarray}

Using the asymptotic expressions derived in Ref.\cite{Dong:2011nlo} and the relations among the same polarization combination $(\lambda_1,\lambda_2)$ with different $J$, the non-conformal NLO coefficients $B^{J(\beta)}_{\lambda_1,\lambda_2}$ and the conformal NLO coefficients $B^{J(con)}_{\lambda_1,\lambda_2}$ at the renormalization scale $\mu_R$ can be written as:
\begin{eqnarray}
B^{0(\beta)}_{0,0} &=& B^{2(\beta)}_{0,0}={1 \over 2} \bigg(\ln\frac{\mu^2_R}{s} +{8\over 3}+ 2\ln2 \bigg), \\
B^{0(\beta)}_{1,0} &=& B^{1(\beta)}_{1,0}=B^{2(\beta)}_{1,0}={1 \over 2}\bigg( \ln\frac{\mu^2_R}{s} + {17\over 9} + 2\ln2 \bigg), \\
B^{1(\beta)}_{0,1} &=& B^{2(\beta)}_{0,1}={1 \over 12}\bigg(
6\ln\frac{\mu^2_R}{s} + 12\ln2 + 13 \bigg), \\
B^{1(\beta)}_{1,1} &=& B^{2(\beta)}_{1,1}= {1 \over 12}\bigg(6\ln\frac{\mu^2_R}{s} + 12\ln2 + 13 \bigg), \\
B^{2(\beta)}_{1,2} &=& {1 \over 2}\bigg( \ln\frac{\mu^2_R}{s} + {5\over 3} + 2\ln2 \bigg)
\end{eqnarray}
and
\begin{widetext}
\begin{eqnarray}
B^{0(con)}_{0,0} &=& -{2\over 3} (4-\ln2) \ln r - \frac{1}{9} ( 46 + \pi^2 - 40\ln2 + 33 \ln^2 2), \\
B^{0(con)}_{1,0} &=& {2\over 3} \ln^2 r - {1 \over 54}(139-104\ln2)\ln r - {1\over 27}\bigg( 161 + {8\pi^2\over 3}- {495\over 2}\ln2 + 100 \ln^2 2 \bigg), \\
B^{1(con)}_{1,0} &=& {-1\over 6 r} \bigg(5 \ln^2r + (7-2\ln2)\ln r-19+ 2\pi^2 + 75\ln2- 21 \ln^2 2\bigg), \\
B^{1(con)}_{0,1} &=& {1\over 12}\bigg( \frac{25}{2} \ln^2 r - (46-99\ln2)\ln r - {1\over 6} (616 + 74\pi^2 - 1696\ln2 + 303 \ln^22 )\bigg), \\
B^{1(con)}_{1,1} &=& {1\over 12}\bigg( 10 \ln^2r + 2(1+17\ln2)\ln r - \frac{1}{3}( 266 + 7\pi^2 - 128\ln 2 + 147 \ln^2 2)\bigg). \\
B^{2(con)}_{0,0} &=& -{2\over 3}(4-\ln2) \ln r -\frac{1}{9} ( 64 + \pi^2 + 104\ln 2 + 33 \ln^22), \\
B^{2(con)}_{0,1} &=& {1\over 6} \bigg( \frac{13}{2}\ln^2 r - (22-43\ln2) \ln r - \frac{1}{6} ( 284 + 30\pi^2 - 380\ln2 + 159 \ln^2 2)\bigg), \\
B^{2(con)}_{1,0} &=& -{1\over 3} \bigg(2\ln^2 r +\frac{1}{6}(5+8\ln2) \ln r  -\frac{1}{18} ( 291-8\pi^2 + 171 \ln 2 + 312\ln^2 2 )\bigg), \\
B^{2(con)}_{1,1} &=& {1\over 12} \bigg( 4\ln^2 r - (46-62\ln2) \ln r  - \frac{1}{3}(274 + 27\pi^2 - 316\ln 2 + 9\ln^2 2)\bigg), \\

Posted on 1st August 2014 by Pavlov in Features // 4 Comments
Pat Lawlor is, quite simply, a pinball design legend. He's Pavlov Pinball's favourite designer, and he is many other pinheads' favourite as well.
So everyone at Pavlov Pinball was jumping up and down with excitement like a wagon-load of monkeys when it was announced – back in January of this year – that Lawlor is to design Jersey Jack Pinball's next machine after The Hobbit is released. But since then there's been precious little further information.
Jersey Jack Guarnieri
Yesterday Pavlov Pinball caught up with Jersey Jack himself – Jack Guarnieri – and took the opportunity to get the latest on what Lawlor has been up to since the announcement.
First of all, what's the new game going to be called, and what's it about? Not surprisingly Guarnieri is not giving that away for the moment, and probably won't till The Hobbit is out the door. No amount of monkey-like behaviour will persuade him to do so. He did reiterate that it's an original theme rather than a licensed title, and that the idea for the theme came from Lawlor.
But it turns out that the idea for the theme is just one of many that were fomenting in the Lawlor's brain.
Pat Lawlor joined JJP in early 2014
"When I met with Pat a year ago, he didn't have anything he had been working on. That was good because I didn't want something that he had thought up three years previously," says Guarnieri.
What happened, he says, is that Lawlor had three new game ideas that he wanted to pitch to Jersey Jack Pinball. But after Lawlor outlined his first one, Guarnieri was sold on it.
"We never got to the second or third idea. If you have the Sistine Chapel and it needs painting and Michelangelo wants to do the work, you're not going to tell him what you want him to do, you just let him get on with it" he says.
Lawlor's The Addams Family – surpassed only by Twilight Zone?
How is the game getting along? Quite nicely, apparently. Just two weeks ago Guarnieri paid a visit to Lawlor's studio, and got to play a flipping whitewood. "It's just amazing," he says. "There's lots of action, lots of strategy, and some great shots. In a way it is a licensed game, but in this case the license is Pat Lawlor, along with (artist) John Youssi and (mechanical designer) John Krutsch." EDIT on 2nd August 2014: Guarneri commented: "Don't forget Original Art by John Youssi and Software from Ted Estes and Keith Johnson and Soundmaster David Thiel rounding out the Team!"
Everyone knows that sinking feeling when they see the sequel to a great movie and the sequel bears almost no resemblance to the original apart from the name. So what every fan of The Addams Family, Twilight Zone and Lawlor's other masterpieces wants to know is this: will the new game be recognisably a Pat Lawlor game? Would a Lawlor fan who came across the new game without knowing anything about it know that it was his work? Will it be more of the Williamsy type of goodness that most Lawlor fans love?
The good news is that – according to the ebullient Guarnieri at least – the answer is yes, only more so. "It has his fingerprints all over it, but it will stand on the shoulders of what he has created in the past," he says. "There's a reason why this guy is the best – he is a craftsman."
Guarnieri likens Lawlor's work to Michelangelo's
Anyone who knows Jersey Jack will vouch for the fact that he's never less than totally upbeat about everything he's involved in. Nevertheless, if you're a Lawlor fan then this all sounds very promising. It's well over twenty years since the Lawlor classics like Funhouse, TAF and TZ were released, and six years since his most recent Stern games saw the light of day. The end of the wait for the next one may soon be in sight.
That leaves just one final question to put to Jersey Jack: Will the new game have a second right flipper in the upper part of the playfield – a feature of the three Lawlor masterpieces (TAF, TZ and No Good Gofers) that are currently set up in Pavlov Towers?
Guarnieri pauses for a second, as if wondering what he can reveal. Then he smiles. "Yes," he says, "it will."

Interesting news/tease, something to look forward to! BTW, no such word as 'formenting.' I think you mean 'fomenting' and confused it with 'fermenting.' Spellcheck is sometimes your friend.

Fundraising for Derain House
Prior to 1991 there were no dedicated respite or palliative support facilities in Lancashire for families of children with life shortening conditions, and it was in response to a plea for funding for a children's hospice from the Haydock family from Leyland, whose son Derek was suffering from a life threatening condition, that the concept of Derian House was born.
The Haydock family launched their Fundraising Campaign and raised a fantastic £25,000 towards the capital cost of the hospice. However, with a life threatened child to care for in addition to their fundraising efforts, the family and their group of committed supporters, who later went on to form the Leyland Support Group, realized that the project to build a hospice on such a scale was beyond their capabilities and they approached Ed Wraith, a Senior Paediatrican at the Royal Manchester Children's Hospital at Pendlebury, and Derek Haydock's consultant, for help and advice.
At his request, in 1991, the Chairmanship of the Appeal to build Derian House was taken on by local professional and businesswoman, Margaret Vinten, a role which she wholeheartedly embraced.
Visiting families throughout the region who were struggling to cope with the trauma of caring for a child with a life shortening illness, and speaking to staff at other children's hospices in Yorkshire and beyond, who explained that without the facilities they provided, families faced an extremely uncertain future, she determined that Derian House was no longer an optional extra, but an absolute necessity.
With this in mind, she recruited the support of friends, benefactors, celebrities, companies and organisations throughout the region, all of whom got behind the fundraising campaign. With their help, she succeeded in driving forward the highly successful Capital Appeal from its concept to its conclusion, with the completed hospice, its name a combination of the Haydock brothers' names Derek and Ian, opening in October 1993.
Since then, the hospice has developed a partnership of care with families which is sensitive to the needs of the whole family in providing an approach to care and support as individual as they are.
There is no doubt, it is this individualistic approach, tailored to the needs of each family, and developed in association with contact teams and key worker support systems, that ensures a structured support facility whilst acknowledging and respecting parents as the primary carer in each and every situation.
In looking back over the past twenty four years, and all that has been achieved, we also look forward to the future and the fresh challenges it will bring. Whatever those challenges may be, we will continue to do our utmost in striving to meet the highest standards of care, and the needs of the many families who depend on Derian House for the care and support it provides for them and their children.

Pensioner sold his house with massive discount but there's a catch
Peter Yielding, 64, put his neat three-bed semi in pricey St Albans on the market for £350,000 - hundreds of thousands of pounds less than other homes on the street
by Joe Mellor
in Property
A savvy pensioner has sold his house with a massive discount but there's a catch – he's successfully demanded he can continue to live there – RENT FREE.
Peter Yielding, 64, put his neat three-bed semi in pricey St Albans on the market for £350,000 – hundreds of thousands of pounds less than other homes on the street.
The online listing states it has a garage, driveway and would be perfect for investors.

But the description on Right Move stated: "The current vendor would like to remain at the property rent free as a long term tenant."
And despite the odd request, Mr Yielding said he's managed to attract TWO "firm offers" from buyers who are happy to let him say, and he's going to sell.
Speaking at his home this week, he said: "[I'm selling because] I just need the money if I'm honest with you.
"I'll live [here] as a tenant."

At £350,000, it is a bargain compared to the last house that sold on the street, which went for £607,500 in January, and another that sold for £550,000 last September.
The average cost of a house in the area late last year was around £560,000, and St Albans was recently voted the top commuter city for London.
Reddit user riverY90 mocked the deal, asking: "How did they not get laughed out of the estate agents? Which estate agent would even bother trying?
"Why do they think this is a good investment for someone?"
But not everyone agreed.
User In-for-a-penny said the deal was "possibly not as ridiculous as it first appears".
They explained: "St Albans is posh and close to London – £350k is substantially less than what that gaff is worth.
"I'd take on a long term tenant for around £200,000, or whatever the difference in value is."
Rdditor Mossley agreed that it might be a good investment, saying: "I'd consider it.
"You get to own a property and it'll only increase in value over time.
"The deciding factor would be the age / life expectancy of the occupant – mid twenties probably not, mid nineties almost certainly. It'd all be assuming a cash sale too, and no mortgage to pay."
Although it may sound bizarre, the practice is called "home reversion" and is actually not that uncommon.
In a home reversion you sell all or part of your house for cheap – typically 30% to 60% less than the market value – for a cash lump sum, a regular income or both.
The buyer allows you to keep living there until you die or move into care.
The older you are when you sell, the higher the percentage you'll get of your home's market value.
This can work well for both parties but it can come back to bite buyers, like in one famous case where an unlucky man purchased a house from the world's oldest woman.
Andre-Francois Raffray thought he had a great deal when he agreed to pay 90-year-old Jeanne Calment a monthly fee until she died, when he'd get her grand apartment in the south of France.
But Mrs Calment ended up living another 32 years, becoming the world's oldest woman reaching an age of 122.
She actually outlived Mr Raffray, who paid her more then double the flat's value before he died at age 77 – and on his death his family had to keep paying her.

BP filling stations across London have been shut down by environmental activists.
Campaign group Greenpeace claimed it had shut off the fuel supplies to all stations in the city. The oil company said about 20 had been closed.
BP said activists stopped the flow of fuel by flipping safety switches on forecourts, then removing them to prevent the filling stations reopening.
How long until a break away group decide its a bigger statement to go a little bit further ?
Intended terrorism, probability very low.
Causing an accident by tampering with equipment, probability high.
They'll have to go a long way to get anywhere close to the eco-terrorism B.P. have committed.
There's something to this.If such action were entirely accidental than how come goldman sachs and a few other establishments offloaded a shedload of shares three months prior to the incident?
enviro-fascism was always intended to be one avenue into the centrally-planned socialist society.
the powers that be have lots of technology and patents for ideas that would MASSIVELY reduce our fossil fuel dependence,but the gizmo's are not being deployed.
one has to suspect that this stuff only gets drip-fed into the system so as to maintain a means of control of the populace.
...that's why we get legislation instead of innovation.
Environmentalism is all but a recognised religion now. As with all slightly loony religions I'm sure it will have its fair share of fanatics and martyrs.
Environmentalism can be summed up in the phrase 'don't sh*t where you eat'. Anyone with any common sense is an environmentalist.
The idea that we are separate from our environment and don't rely on it for, well, basically everything of value - water, food air etc., is more akin to religious delusion.
I was thinking of these tree hugger types . . .
But that has nothing to do with the modern Green movement. The commies have co-opted Environmentalism just as they co-opt any organised movement they get their hooks into, to the point where its only purpose today is to push their far-left goals.
Those are pointless generalisations. There are as many shades of environmentalism as there are capitalism, socialism or liberalism.
But there are also simple questions - who is damaging our planet and therefore us and our ability to live?. Who are the terrorists?
If the technology exists and is not being deployed, how is that enviro-fascism? How is the population being controlled?
The Mash right on the money as usual.
Fly - to - Let ?
However there are a few things that simply are right and indisputable, such as our need for clean water, clean air and land to grow food. We either have them, or we die. This is the basis of environmentalism. It's not a matter of knowing better than anyone, as everyone knows this already - as I said, it's common sense.
The problem is that our culture perpetuates the fantasy that we are separate from such things. The fact that environmentalism or a 'green' movement even exists is an indication of how f*cked our culture is, like we need to have these things pointed out to us.
I've noticed it's becoming almost de riguer amongst the anti-AGW crowd to boast of their huge petrol consumption, lack of recycling, etc. Posting these kinds of comments is an assertion of their level of anti-greenness.
They tend not to understand satire either..
Are you sure about that, Anthony Watts of www.wattsupwiththat.com (Best Science Blog) has a Prius . Personally I got rid of my car a few years ago, don't fly, walk to work and am probably "greener" (whatever that means) than 90% of the mentalists.

Rome mayor vetoes Olympic bid
Raggi says "irresponsible" for city to bid for 2024 Olympics.
Rome mayor Virginia Raggi has said the city will withdraw its bid to host the 2024 Olympics, confirming her long-held opposition to the candidacy.
The mayor, a member of the anti-establishment Movimento 5 Stelle (M5S), announced her decision on 21 September after failing to attend an earlier scheduled appointment with Giovanni Malagò, the head of Italian Olympic Committee CONI.
His delegation was kept waiting 35 minutes before walking out without meeting the mayor.
Raggi motivated her decision on cost grounds, saying it would be "irresponsible" for Rome to bid for the 2024 Olympics and that the funds would be better spent on city services.
She claimed that Romans were still paying the debts from Rome's 1960 Olympics – a claim that Malagò subsequently denied.
Rome's Olympic bid was submitted last September by former mayor Ignazio Marino and bid leader Luca Cordero di Montezemolo, with the strong approval of Italian premier Matteo Renzi and the local business community.
Raggi's decision to oppose Rome's bid to host the 2024 Olympics leaves only Los Angeles, Paris and Budapest in the running.
The International Olympic Committe (IOC), which requires bidders to have the support of both the government and the city, will announce the host city in September 2017.
