Latest results from CMS presented at ICHEP 2016

2016-08-08, by Cms People

Figure 1: Mass spectra obtained in the 2016 CMS Higgs search using the di-photon (left) and four-lepton (right) decays channels. The significance of the observed signals around 125 GeV is larger than 5 standard deviations in both channels. The analysed data correspond to an integrated luminosity of 13 fb<sup>&minus;1</sup>, collected with the CMS detector at a centre-of-mass energy of 13 TeV.
