Title: Search for a Higgs boson in the mass range from 145 to 1000 GeV decaying to a pair of W or Z bosons

Abstract

A search for a heavy Higgs boson in the H → WW and H → 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 √s = 7 TeV and up to 19.7fb–1 at √s = 8 TeV, recorded by the CMS experiment at the CERN LHC. Several final states of the H → WW and H → 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 < mH < 1000 GeV. In addition, we interpret the results in the context of an electroweak singlet extension of the standard model.

Table 1 Table 1: A summary of the analyses included in this paper. The column “H production” indicates the production mechanism targeted by an analysis; it does not imply 100% purity in the selected sample. The main contribution in the untagged categories is always ggF. The (jj)VBF refers to a dijet pairmore » consistent with the VBF topology. (jj)W(Z) and (J)W(Z) refer to a dijet pair and single merged jet from a Lorentz-boosted W (Z) with an invariant mass consistent with a W (Z) dijet decay, respectively. The superscript “0,1,2 b tags” refers to the three possible categories of b tag multiplicities. Exclusive final states are selected according to the lepton and reconstructed jet content of the event. The mass range under investigation and the mass resolution are also listed. Mass ranges differ with the sensitivities of each channel.« less
