Search for Anomalous Higgs and Vector Boson Couplings in Proton-Proton Collisions at √s = 13 TeV

This dissertation presents a search for anomalous Higgs and vector boson couplings with ZZH VBS events. The 2016-2018 Run II period for the CMS detector at CERN's LHC provides a dataset with an integrated luminosity of 137fb^-1 of 13TeV center of mass energy proton-proton collisions. This analysis sets bounds on K2V, the ratio of the quartic Higgs-gauge coupling (HHVV) parameter to its standard model value, as $-2.25

本论文针对ZZH矢量玻色子散射（Vector Boson Scattering, VBS）事例中的反常希格斯（Higgs）与矢量玻色子耦合开展研究。欧洲核子研究中心（CERN）大型强子对撞机（Large Hadron Collider, LHC）上的紧凑缪子线圈（CMS）探测器在2016至2018年运行二期（Run II）期间，采集了质心系能量为13TeV的质子-质子碰撞数据集，其积分亮度为137fb⁻¹。本分析针对K2V参数设置了约束边界——该参数为四次希格斯-规范耦合（HHVV）参数相对于其标准模型（Standard Model, SM）取值的比率，约束结果为$-2.25$
