Abstract

ThemassoftheHiggsbosonismeasuredintheH→ZZ∗→4l and in the H→γγ decay channels with 36.1fb−1of proton–proton collision data from the Large Hadron Collider at acentre-of-mass energy of 13 TeV recorded by the ATLAS detector in 2015 and 2016.The measured value in the H→ZZ∗→4l channel is mZZ∗H =124.79±0.37 GeV, while the measured value in the H→γγ channel is mγγH=124.93±0.40 GeV. Combining these results with the ATLAS measurement based on 7and 8TeV proton–proton collision data yields a Higgs boson mass of mH=124.97±0.24 GeV.
