Measurement of the properties of a Higgs boson in the four-lepton final state

Abstract: The properties of a Higgs boson candidate are measured in the H→ZZ→4l decay channel, with l=e,μ, using data from pp collisions corresponding to an integrated luminosity of 5.1 inverse femtobarns at center-of-mass energy of s√=7 TeV and 19.7 inverse femtobarns at s√=8 TeV, recorded with the CMS detector at the LHC. The new boson is observed as a narrow resonance with a local significance of 6.8 standard deviations, a measured mass of 125.6±0.4 (stat.) ±0.2 (syst.) GeV, and a total width less than 3.4 GeV at a 9… Show more

“…The set of experimental results and specific Higgs channels that we use for the Higgs signal limit, can be found in Refs. [124][125][126][127][128][129][130][131][132][133]. For a complete list of the results used in the exclusion bounds analysis, see [121] and references therein.…”

“…The properties of a Higgs boson candidate are measured in the H → ZZ → 4 decay channel, with = e, μ, using data from pp collisions corresponding to an integrated luminosity of 5.1 fb at the LHC [3]. This channel has a very low branching ratio (BR ∼ 10 −4 ); however, it was the "golden" channel for the Higgs discovery, because of its high resolution (only leptons, fully reconstructed final state) and high signal over background ratio.…”
