| Abstract: A measurement of the Higgs boson mass in the diphoton decay channel is performed using proton-proton collision data at a centre-of-mass energy of 13 TeV. The dataset recorded with the CMS detector between 2016 and 2018 is used, corresponding to an integrated luminosity of 138 $ \textrm{fb}^{-1} $. A refined detector calibration and new analysis techniques have been used to improve the precision of these results over earlier measurements. The Higgs boson mass is measured to be $ m_{\textrm{H}} = $ 125.14 $ \pm $ 0.10 $ \textrm{(stat)} \pm 0.11 \textrm{(syst)} \textrm{GeV} $. In addition, a combination with the Run 1 mass measurement at 7 and 8 $ \textrm{TeV} $ in the diphoton final state is performed resulting in $ m_{\textrm{H}} = $ 125.07 $ \pm $ 0.09 $ \textrm{(stat)} \pm 0.10 \textrm{(syst)} \textrm{GeV} $. | ||
