Measurements of Higgs Boson Production and Properties in Di-photon Decay Channel Using Data Collected by CMS Detector at Center of Mass Energy of 13 TeV

摘要

45.1 Introduction In the year 2012, during RunI at LHC, a Standard Model Higgs boson like particle was discovered by the CMS collaboration. Further studies are being made with the goal to measure the properties of the newly measured particle. Among the different decay channels, H yy has a very small branching ratio (0.2%). Still the clear final state topology makes it the most sensitive channel for study of the Higgs boson. In the report we discuss the first measurements with data collected by CMS in the year 2016 during LHC Runll at center of mass energy of 13 TeV corresponding to integrated luminosity of 12.9 fb~(-1).
