Abstract
The most recent results of a Higgs boson production and properties from the CMS Collaboration using the LHC Run 1 and Run 2 data are reported. These include analyses of a Higgs boson decaying to a pair of photons, four leptons via Z boson pair decays and the associated production of a Higgs boson with top quark pair, predicted by the Standard Model (SM). The studies of a Higgs boson decays to a pair of bottom quarks, a pair of tau leptons and a charm quark pair are also presented. The Higgs boson production via vector boson fusion (VBF) and decaying to invisible particles is reported here as well. The analysis of a Higgs boson decay to a pair of muons is also presented. The study of a Higgs boson pair production at 13 TeV is performed as well and projections of a Higgs boson self couplings together with the couplings to other particles at the HL-LHC are made.
Highlights
The Higgs boson was discovered in 2012 at CERN by the ATLAS and CMS Collaborations [1,2,3], with mass measured to be around 125 GeV and precise measurements of its spin-parity, width, boson and fermion couplings were pursued ever since the discovery
With the full LHC Run 2 data available, the focus of the Higgs boson studies shifted from the Higgs boson discovery to the precision measurements of the Higgs boson couplings and properties
The analysis of a Higgs boson decaying to two photons was performed targeting the gluongluon fusion and the vector boson fusion (VBF) production modes, using the data recorded by the CMS experiment in 2016 and 2017 [5]
Summary
The Higgs boson was discovered in 2012 at CERN by the ATLAS and CMS Collaborations [1,2,3], with mass measured to be around 125 GeV and precise measurements of its spin-parity, width, boson and fermion couplings were pursued ever since the discovery. The analysis of a Higgs boson decaying to two photons was performed targeting the gluongluon fusion (ggF) and the vector boson fusion (VBF) production modes, using the data recorded by the CMS experiment in 2016 and 2017 [5]. The decay of a Higgs boson to four leptons, being either electrons or muons, via production of a Z boson pair has a clean experimental signature with a large signal to background ratio, due to an excellent lepton momentum resolution. It provides a possibility for a precise measurement of the Higgs boson mass and width
