Description

A search for additional Higgs-like bosons in the H to WW and H to ZZ decay channels is reported, for Higgs boson masses in the range 145 < m_H < 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 sqrt(s) = 7 TeV and up to 19.3 fb-1 at sqrt(s) = 8 TeV, recorded by the CMS experiment at the LHC. Several final states of the H to WW and H to ZZ decays are analyzed. Upper limits for the search for a heavy resonance in the context of an electroweak singlet extension of the standard model are presented. Additionally, the combined upper limits at 95% confidence level on the products of the cross section and branching fraction exclude a standard-model-like Higgs boson in the range 145 < m_H < 1000 GeV
