The mass of the Higgs boson is measured in the H → Z Z ∗ → 4` and in the H → γγ decaychannels with 36.1 fb −1 of 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. TheZ Z ∗ = 124.79 ± 0.37 GeV, while themeasured value in the H → Z Z ∗ → 4` channel is m Hγγmeasured value in the H → γγ channel is m H = 124.93 ± 0.40 GeV. Combining theseresults with the ATLAS measurement based on 7 and 8 TeV proton-proton collision datayields a Higgs boson mass of m H = 124.97 ± 0.24 GeV.
