Abstract (data abstract)
A measurement of the mass of the Higgs boson in the diphoton decay channel is presented. This analysis is based on 35.9 fb$^{-1}$ of proton-proton collision data collected during the 2016 LHC running period, with the CMS detector at a center-of-mass energy of 13 TeV. A refined detector calibration and new analysis techniques have been used to improve the precision of this measurement. The Higgs boson mass is measured to be $m_{H}$ = 125.78 +/- 0.26 GeV. This is combined with a measurement of $m_{H}$ already performed in the H to ZZ to 4l decay channel using the same data set, giving $m_{H}$ = 125.46 +/- 0.16 GeV. This result, when further combined with an earlier measurement of $m_{H}$ using data collected in 2011 and 2012 with the CMS detector, gives a value for the Higgs boson mass of $m_{H}$ = 125.38 +/- 0.14 GeV. This is currently the most precise measurement of the mass of the Higgs boson.
