论文摘要
提出了Higgs玻色子产生的测量,其中Higgs玻色子衰减成一对$τ$ Leptons,使用了用CMS实验收集的质子 - 蛋白质碰撞样本,该质子质子碰撞样本在13 TEV的CMS实验中,对应于138 Fb $^{-1} $ 138 fb $^{-1} $。提出了三个分析。两个是通过Gluon Fusion和Vector Boson Fusion靶向Higgs玻色子的产生:基于神经网络的分析和基于对信号比率与背景事件比率优化的事件分类的分析。这些靶向载体玻色子相关的希格斯玻色子产生的分析得到了补充。相对于标准模型预测和横截面的标准模型预测和产物,在多达16个不同的运动区域中以信号强度的形式介绍了信号强度的形式。为了同时测量基于神经网络的分析和靶向载体相关的higgs玻色子生产信号强度的分析,发现包括Higgs Boson的生产为0.82 $ \ pm 0.11,0.67 $ \ pm $ $ \ pm $ 0.19(0.81 $ \ pm $ 0.17)的Mainn $ $ $ $ $ $ $ $ $ 1.载体玻色子相关的希格斯玻色子产生0.45。
Measurements of Higgs boson production, where the Higgs boson decays into a pair of $τ$ leptons, are presented, using a sample of proton-proton collisions collected with the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. Three analyses are presented. Two are targeting Higgs boson production via gluon fusion and vector boson fusion: a neural network based analysis and an analysis based on an event categorization optimized on the ratio of signal over background events. These are complemented by an analysis targeting vector boson associated Higgs boson production. Results are presented in the form of signal strengths relative to the standard model predictions and products of cross sections and branching fraction to $τ$ leptons, in up to 16 different kinematic regions. For the simultaneous measurements of the neural network based analysis and the analysis targeting vector boson associated Higgs boson production signal strengths are found to be 0.82 $\pm$ 0.11 for inclusive Higgs boson production, 0.67 $\pm$ 0.19 (0.81 $\pm$ 0.17) for the production mainly via gluon fusion (vector boson fusion), and 1.79 $\pm$ 0.45 for vector boson associated Higgs boson production.
