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