Search for a standard-model-like Higgs boson with a mass in the range 145 to 1000 GeV at the LHC

TL;DR

This paper reports a search for a standard-model-like Higgs boson in the mass range 145 to 1000 GeV using CMS data from the LHC, setting new exclusion limits that extend previous bounds.

Contribution

It provides the first comprehensive search across a wide mass range, extending exclusion limits for the Higgs boson up to 710 GeV.

Findings

Excluded Higgs masses from 145 to 710 GeV at 95% confidence level.

Extended the excluded mass region from previous limits.

Used proton-proton collision data at 7 and 8 TeV from the CMS experiment.

Abstract

A search for a standard-model-like Higgs boson 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 inverse femtobarns at sqrt(s) = 7 TeV and up to 5.3 inverse femtobarns at sqrt(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 < m[H] < 710 GeV, thus extending the mass region excluded by CMS from 127-600 GeV up to 710 GeV.
