AI 中文摘要
本研究利用质心能量为13 TeV的质子-质子碰撞数据，开展双光子衰变道的希格斯玻色子质量测量，所用数据为CMS探测器在2016年至2018年期间记录，对应积分亮度为138 fb⁻¹。相较于早期测量，研究采用了改进的探测器校准方法与新的分析技术，以提升结果的精度。测得希格斯玻色子质量m_H = 125.13 ± 0.15 GeV，其中统计不确定度为±0.10 GeV，系统不确定度为±0.12 GeV；此外，将该结果与质心能量7 TeV和8 TeV下双光子末态的质量测量结果进行组合，得到m_H = 125.06 ± 0.14 GeV，其中统计不确定度为±0.09 GeV，系统不确定度为±0.11 GeV。
英文摘要
A measurement of the Higgs boson mass in the diphoton decay channel is performed using proton-proton collision data at a center-of-mass energy of 13 TeV. The data set recorded with the CMS detector between 2016 and 2018 is used, corresponding to an integrated luminosity of 138 fb$^{-1}$. A refined detector calibration and new analysis techniques are employed to improve the precision of the results compared to earlier measurements. The Higgs boson mass is measured to be $m_\mathrm{H}$ = 125.13 $\pm$ 0.15 GeV = 125.13 $\pm$ 0.10 (stat) $\pm$ 0.12 (syst) GeV. In addition, a combination with the mass measurement at center-of-mass energies of 7 and 8 TeV in the diphoton final state is performed resulting in $m_\mathrm{H}$ = 125.06 $\pm$ 0.14 GeV = 125.06 $\pm$ 0.09 (stat) $\pm$ 0.11 (syst) GeV.
