CMS Measurements of the Higgs-like Boson In the Two Photon Decay Channel

Abstract

CMS reports on the recently updated, preliminary results with the full datasets of 2011 and 2012 in the analysis of the Higgs-like Boson at 125 GeV. Utilizing 5.1$fb^{-1}$ of 7 TeV data and 19.6$fb^{-1}$ of 8 TeV data, a signal strength of $0.78^{+0.28}_{-0.26}$ times the Standard Model (SM) expectations with a mass of $125.4\pm0.8$ GeV is observed. The significance of this resonance with respect to the background only prediction is $3.2\sigma$. The cut-based cross-check analysis observes signal strength of $1.11^{+0.32}_{-0.30}$ times the SM expectations with a significance of $3.9\sigma$ at 124.5 GeV.
