The first studies performed by the CMS collaborations of the properties of the recently discovered Higgs boson candidate are presented. The data sample considered corresponds to the integrated luminosity delivered by the LHC up to September 2012, 5.1 fb−1 at √s=7 TeV and 12.1 fb−1 at 8 TeV. The significance of the signal results 6.9 σ. The mass is measured to be 125.8 ±0.4 (stat) ±0.4 (syst) GeV. The individual analysis channels are combined and tested in various ways against the predictions of the SM in terms of the coupling structure, observing in all the cases a good agreement. Under the assumption that the observed boson has spin zero, the data disfavour the pseudo-scalar hypothesis 0− with a CLs value of 2.4%.
