摘要：

基于欧洲核子研究中心（CERN）大型强子对撞机（LHC）的ATLAS和CMS实验在$H \rightarrow γγ$和$H \rightarrow ZZ\rightarrow 4\ell$衰变通道中的组合数据样本，给出了对希格斯玻色子质量的测量。结果是从两个通道和两个实验中的重建不变质量峰的同时拟合获得的。从个别通道和两个实验的测量质量被发现是一致的。希格斯玻色子的总质量是$m_{H} = 125.09\pm0.21\,\mathrm{(stat.)}\pm0.11\,\mathrm{(syst.)}~\mathrm{GeV}$。

英文摘要：

A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the $H \rightarrow γγ$ and $H \rightarrow ZZ\rightarrow 4\ell$ decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual channels and the two experiments are found to be consistent among themselves. The combined measured mass of the Higgs boson is $m_{H} = 125.09\pm0.21\,\mathrm{(stat.)}\pm0.11\,\mathrm{(syst.)}~\mathrm{GeV}$.
