The measured value in the H→ZZ⁎→4ℓ channel is mHZZ⁎=124.79±0.37GeV , while the measured value in the H→γγ channel is mHγγ=124.93±0.40GeV . 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±0.24GeV .engMeasurement of the Higgs boson mass in the $H\rightarrow ZZ^* \rightarrow 4\ell$ and $H \rightarrow \gamma\gamma$ channels with $\sqrt{s}=13$ TeV $pp$ collisions using the ATLAS detectorjournal article2019-02-05
