Abstract
A search for a heavy Higgs boson in the $H \to WW$ and $H \to ZZ$ decay channels is reported. The search is based upon proton-proton collision data samples 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 by the CMS experiment at the CERN LHC. Several final states of the $H \to WW$ and $H \to ZZ$ decays are analyzed. The combined upper limit at the 95% confidence level on the product of the cross section and branching fraction exclude a Higgs boson with standard model-like couplings and decays in the range 145 < $m_H$ < 1000 GeV. We also interpret the results in the context of an electroweak singlet extension of the standard model.
