摘要
Results of the measurements of the 125 GeV Higgs boson properties with proton-proton collision data at root s = 13 TeV collected by CMS detector are presented. The used Higgs boson decay channels include the five major decay modes, H -> gamma gamma, H -> ZZ -> 4l, H -> WW -> lvlv, H -> tau(+)tau(-) and H -> b (b) over bar, and two rare decay modes, H -> mu(+)mu(-) and H -> Z/gamma* + gamma -> ll gamma, with l = e, mu. The measured Higgs boson properties include its mass, signal strength relative to the standard model prediction, signal strength modifiers for different Higgs boson production modes, coupling modifiers to fermions and bosons, effective coupling modifiers to photons and gluons, simplified template cross sections, fiducial cross sections. All results are consistent, within their uncertainties, with the expectations for the Standard Model Higgs boson.
