Higgs boson properties and tests of the Standard Model at CMS

The measurements of Higgs boson properties, mass, spin/CP, couplings, off-shell cross sections and constraints on invisible width are summarized and compared with standard model expectations. The analysis is based on pp collision data collected at centre-of-mass energies of 7 and 8 TeV by the CMS experiment at the LHC, corresponding to integrated luminosities of 5 fb−1 and 20 fb−1, respectively.
