摘要

我们提出了对重摩擦子产生的研究,特别是针对在多轻子最终态下WWW, wwz, wzz和zzz过程的产生,在LHC运行2时,CMS探测器在√s = 13TeV下收集了137 fb−1的数据。构建了由同电荷双轻子和三轻子组成的事件选择模型,主要研究了WWW过程,同时研究了四、五、六轻子末态的wwz、wzz和zzz过程。该分析利用传统的基于切割的技术和使用增强决策树的多变量技术。

First observation of production of three massive gauge bosons
We present the search for heavy triboson production, specifically targeting the production of WWW , WW Z , W Z Z and Z Z Z processes in multileptonic final states with 137 fb−1 of data collected by the CMS detector during Run 2 of the LHC at √ s = 13TeV. An event selection consisting of identically charged dileptons and trileptons is constructed to primarily study the WWW process, while the WW Z , W Z Z and Z Z Z processes are explored in four, five and six lepton final states. The analysis utilizes both traditional cut-based and multivariate techniques using boosted decision trees.
