Measurement of the Higgs boson mass with H RIGHTWARDS ARROW γγ decays in 140 fb-1 of s=13 TeV pp collisions with the ATLAS detector
Original language description
The mass of the Higgs boson is measured in the HRIGHTWARDS ARROWγγ decay channel, exploiting the high resolution of the invariant mass of photon pairs reconstructed from the decays of Higgs bosons produced in proton-proton collisions at a centre-of-mass energy s=13 TeV. The dataset was collected between 2015 and 2018 by the ATLAS detector at the Large Hadron Collider, and corresponds to an integrated luminosity of 140 fb-1. The measured value of the Higgs boson mass is 125.17+-0.11(stat.)+-0.09(syst.) GeV and is based on an improved energy scale calibration for photons, whose impact on the measurement is about four times smaller than in the previous publication. A combination with the corresponding measurement using 7 and 8 TeV pp collision ATLAS data results in a Higgs boson mass measurement of 125.22+-0.11(stat.)+-0.09(syst.) GeV. With an uncertainty of 1.1 per mille, this is currently the most precise measurement of the mass of the Higgs boson from a single decay channel.
