Combined measurement of the Higgs boson mass from the H→γγ and H→ZZ∗→4ℓ decay channels with the ATLAS detector using s√ = 7, 8 and 13 TeV pp collision data
A measurement of the mass of the Higgs boson combining the H→ZZ∗→4ℓ and H→γγ decay channels is presented. The result is based on 140 fb−1 of proton-proton collision data collected by the ATLAS detector during LHC Run 2 at a centre-of-mass energy of 13 TeV combined with the Run 1 ATLAS mass measurement, yielding a Higgs boson mass of 125.11 ± 0.09 (stat.) ± 0.06 (syst.) = 125.11 ± 0.11 GeV. This corresponds to a 0.09 % precision achieved on this fundamental parameter of the Standard Model of particle physics.
