Abstract
The studies of the properties of the recently found boson performed by CMS are presented. The analyses reported here use the data sample of 5.1 fb−1 at √s = 7TeV and 12.1 fb−1 at √s = 8TeV delivered by LHC and collected by the CMS experiment. The background-only hypothesis is excluded with a 6.9σ significance. The mass of the new boson is measured to be 125.8 ± 0.4(stat) ± 0.4(syst) GeV/c2, combining the diphoton and four lepton channels. Several spin and intrinsic parity hypotheses are tested. The SM coupling structure is tested combining the measurements in all the considered final states, and a good Agreement is found with the Standard Model predictions.
