CMS High mass WW and ZZ Higgs search with the complete LHC Run1 statistics
A search for the decay of a heavy Higgs boson in the H$\to$ZZ and H$\to$WW channels is reported, analyzing several final states of the H$\to$ZZ and H$\to$WW decays. The search used proton-proton collision data corresponding to an integrated luminosity of up to 5.1 fb$^{-1}$ at $\sqrt{s} = 7$ TeV and up to 19.7 fb$^{-1}$ at $\sqrt{s} = 8$ TeV recorded with the CMS experiment at the CERN LHC. A Higgs boson with Standard Model-like coupling and decays in the mass range of 145 $< m_H <$ 1000 GeV is excluded at 95\% confidence level, based on the limit on the product of cross section and branching fraction. An interpretation of the results in the context of an electroweak singlet extension of the standard model is reported.
