论文摘要
提出了以电子或MUON和缺少横向动量的最终状态中标准模型（SM）以外的物理搜索。该分析使用质子质子碰撞的数据，在2016 - 2018年在LHC上与CMS检测器收集的质量中心能量，对应于138 fb $^{ - 1} $的综合发光度。没有观察到与SM预测的显着偏差。与模型无关的极限设置在腐烂到Lepton-plus-neutrino最终状态的生产横截面上。在顺序标准模型的框架内，通过电子和元衰减通道的组合结果，质量小于5.7 TEV的W'Boson在95％的置信度下排除了。首次使用LHC数据提出了Sm Precision测试的结果，确定斜力electroweak $ w $参数。这些结果与直接w'共振搜索的结果一起用于扩展复合希格斯方案的现有约束。这是使用HIGGS玻色子测量值以外的LHC数据的结果对组合参数的第一个实验排除。
A search for physics beyond the standard model (SM) in final states with an electron or muon and missing transverse momentum is presented. The analysis uses data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected with the CMS detector at the LHC in 2016-2018 and corresponding to an integrated luminosity of 138 fb$^{-1}$. No significant deviation from the SM prediction is observed. Model-independent limits are set on the production cross section of W' bosons decaying into lepton-plus-neutrino final states. Within the framework of the sequential standard model, with the combined results from the electron and muon decay channels a W' boson with mass less than 5.7 TeV is excluded at 95% confidence level. Results on a SM precision test, the determination of the oblique electroweak $W$ parameter, are presented using LHC data for the first time. These results together with those from the direct W' resonance search are used to extend existing constraints on composite Higgs scenarios. This is the first experimental exclusion on compositeness parameters using results from LHC data other than Higgs boson measurements.
