# Does the Standard Model have a Landau pole?

I have seen the statement that the Standard Model has a Landau pole, or at least it its believed that it does at $\sim 10^{34}$ GeV. Has this actually been proven (at least in perturbation theory, as in QED) or what kind of evidence is there to support this?

@Vibert:  The $\lambda$ result in that paper is interesting, but the $U(1)$ coupling shows no signs of slowing down.  I think right now I'd bet that the Standard Model has at least one Landau pole. – user1504 Feb 20 at 13:16
