论文摘要
标准模型Higgs玻色子腐烂到一对W玻色子的生产横截面是在质子 - 蛋白质碰撞中测量13 TEV的质量中心碰撞。该分析靶向通过Gluon Fusion，Vector Boson Fusion产生的Higgs玻色子，并与W或Z Boson结合。候选事件必须至少具有两个带电的瘦素和中等缺失的横向动量，以至少一个源自Higgs Boson的衰减的W BOSON的靶向事件。结果以简化模板横截面框架以及希格斯玻色子与向量玻色子和费米子的耦合形式以包容性和差分横截面的形式介绍。使用CMS检测器在2016 - 2018年收集的数据集，对应于138 fb $^{ - 1} $的集成光度。信号强度修改器$μ$定义为给定衰减通道与标准模型期望的观察到的生产率的比率为$ $ $ = 0.95 $^{+0.10} _ { - 0.09} $。发现所有结果都与不确定性中的标准模型兼容。
Production cross sections of the standard model Higgs boson decaying to a pair of W bosons are measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis targets Higgs bosons produced via gluon fusion, vector boson fusion, and in association with a W or Z boson. Candidate events are required to have at least two charged leptons and moderate missing transverse momentum, targeting events with at least one leptonically decaying W boson originating from the Higgs boson. Results are presented in the form of inclusive and differential cross sections in the simplified template cross section framework, as well as couplings of the Higgs boson to vector bosons and fermions. The data set collected by the CMS detector during 2016-2018 is used, corresponding to an integrated luminosity of 138 fb$^{-1}$. The signal strength modifier $μ$, defined as the ratio of the observed production rate in a given decay channel to the standard model expectation, is measured to be $μ$ = 0.95 $^{+0.10}_{-0.09}$. All results are found to be compatible with the standard model within the uncertainties.
