论文摘要
提出了希格斯玻色子腐烂到一对光子的包含和微分基准横截面的测量。使用与CMS检测器在LHC处记录的Proton-Proton碰撞数据以13 TEV为中心进行分析，并对应于137 fb $^{ - 1} $的集成光度。包含信托横截面的测量为$σ_\ Mathrm {fid} $ = 73.4 $ _ { - 5.3}^{+5.4} $（stat）$ {} _ { - 2.2}^{ - 2.2}^{+2.4} $ 2.4} $（SYST）$，与标准模型期望为75.4 $ 45.4 $ 4.1。这些测量还在针对不同生产模式的基准区域中进行，并作为描述双爆剂系统的几种可观察到的功能，事件中存在的其他喷气机的数量以及其他运动学可观察物。进行了两个双重差分测量。没有观察到与标准模型期望的显着偏差。
The measurements of the inclusive and differential fiducial cross sections of the Higgs boson decaying to a pair of photons are presented. The analysis is performed using proton-proton collisions data recorded with the CMS detector at the LHC at a centre-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 137 fb$^{-1}$. The inclusive fiducial cross section is measured to be $σ_\mathrm{fid}$ = 73.4 $_{-5.3}^{+5.4}$ (stat) ${}_{-2.2}^{+2.4}$ (syst) fb, in agreement with the standard model expectation of 75.4 $\pm$ 4.1 fb. The measurements are also performed in fiducial regions targeting different production modes and as function of several observables describing the diphoton system, the number of additional jets present in the event, and other kinematic observables. Two double differential measurements are performed. No significant deviations from the standard model expectations are observed.
