Abstract

<p indent=0mm>The Large Hadron Collider (LHC) exhibits the highest colliding energy in the world. The compact muon solenoid (CMS) is one of the main experiments conducted on the LHC, and its objective is to discover the Higgs boson and new particles. In this report, the discovery of the Higgs Boson and the measurements of Higgs properties using CMS RUN2 data were briefly presented. Higgs production modes—ggH, VBF, VH, and ttH—were observed using the CMS, and decay modes— ZZ to four leptons, diphotons, WW, ττ, and bb—were discovered using the CMS. Higgs coupling with vector bosons and third-generation fermions t, b, and τ were measured. Moreover, the Higgs mass, width, decay branching ratio, spin and parity, cross-section, and differential cross-section were studied. The results are consistent with those obtained using the standard model within an error range. The results are mainly obtained using 2016 data, and the errors are large. Nevertheless, the results will be improved when all RUN2 data analyses are published.
