Higgs boson studies at the Compact Muon Solenoid (CMS) with an integrated luminosity of 5 fb−1 at 7TeV and up to 12.2 fb −1 at 8TeV in the center of mass are presented. After a brief description of the CMS detector and production and decay of the Higgs boson at the LHC, the main Higgs analyses at CMS are described: H → γγ, H → ZZ, H → W+W−, H → b¯ b, H → τ+τ−. The statistical combination of the results from all channels is presented. The new particle existence is now well established, with an observed significance of 6.9σ, a signal strength μ = 0.88 ± 0.21 times the standard model and a measured mass mH = 125.8±0.4(stat.)±0.4(syst.) GeV. No significant deviation from the standard model Higgs boson hypothesis was found.
