Abstract
The mass of the Higgs boson is measured in the H → Z Z∗ → 4 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∗ → 4 channel is mZ Z∗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 7 and 8 TeV proton–proton collision data yields a Higgs boson mass of mH = 124.97 ± 0.24 GeV.| File | Dimensione | Formato | |
