Abstract

A search for a standard-model-like Higgs boson in the H → WW and H → ZZ decay channels is reported, for Higgs boson masses in the range 145 < mH < 1000 GeV. The search is based upon proton-proton collision data samples corresponding to an integrated luminosity of up to 5.1 fb−1 at √s = 7 TeV and up to 5.3 fb−1 at √s = 8 TeV, recorded by the CMS experiment at the LHC. The combined upper limits at 95% confidence level on products of the cross section and branching fractions exclude a standard-model-like Higgs boson in the range 145 < mH < 710 GeV, thus extending the mass region excluded by CMS from 127–600 GeV up to 710 GeV.
