dc.description.abstract Observation of the diphoton decay mode of the recently discovered Higgs boson and measurement of some of its properties are reported. The analysis uses the entire dataset collected by the CMS experiment in proton-proton collisions during the 2011 and 2012 LHC running periods. The data samples correspond to integrated luminosities of 5.1(Equation Present) and 19.7(Equation Present). A clear signal is observed in the diphoton channel at a mass close to 125(Equation Present)A with a local significance of (Equation Present), where a significance of (Equation Present) is expected for the standard model Higgs boson. The mass is measured to be (Equation Present), and the best-fit signal strength relative to the standard model prediction is (Equation Present). Additional measurements include the signal strength modifiers associated with different production mechanisms, and hypothesis tests between spin-0 and spin-2 models.
