摘　　要：在标准模型中,Higgs场结合电弱对称自发破缺机制赋予基本粒子质量,同时Higgs玻色子的存在保证了有质量的矢量玻色子散射过程的幺正性不被破坏.矢量玻色子散射过程除了对验证Higgs机制具有重要意义,还可以作为寻找标准模型之外的新物理的探针.本文将在简要回顾标准模型中Higgs理论之后,详细地介绍从基于蒙特卡罗样本对两个同电荷W玻色子散射的早期研究,到利用CMS实验一期和二期取数对矢量玻色子散射过程的寻找和利用该过程对超出标准模型的新物理进行的研究,以及近期CMS实验组实现的LHC上第一次对矢量玻色子散射过程的极化部分的测量.Triggered by the electroweak symmetry spontaneous breaking,the Higgs Boson provides mass to fundamental particles and ensures the unitarity safety of the vector Boson scattering.This scattering is crucial for testing the Higgs mechanism,and it can also be used to probe new physics beyond the standard model.In this paper,after a brief introduction of the standard model Higgs theory,we present a detailed review of the research on the vector Boson scattering.This review includes an early study on the two same-charged W Boson based on Monte Carlo samples,the searches for vector Boson scattering and studies on beyond standard model physics using data collected by the compact muon solenoid(CMS)experiment during RunⅠin 2012 and RunⅡin 2016–2018 as well as the recently achieved first measurement of polarized vector Boson scattering.
