论文摘要
据报道，在质子 - 蛋白质碰撞中，在13 tev的质量中心碰撞中，在质子 - 蛋白碰撞中的三个巨大玻色子（VVV = w，z）的联合产生据报道。该分析基于CMS实验在CERN LHC上记录的数据样本，该数据样本对应于137 fb $^{ - 1} $的集成光度。对单个www，wwz，wzz和zzz生产的搜索在最终状态下进行三个，四个，五个，五个和六个lepton（电子或穆斯），或两个相同的leptons加上一两个喷气机。合并的VVV生产信号的观察到（预期）显着性为5.7（5.9）标准偏差，相对于标准模型预测的相应测得的横截面为1.02 $^{+0.26} _ { - 0.23} $。单个www和wwz产生的意义分别为3.3和3.4标准偏差。还报道了单个Triboson过程的测量生产横截面。
The first observation is reported of the combined production of three massive gauge bosons (VVV with V = W,Z) in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis is based on a data sample recorded by the CMS experiment at the CERN LHC corresponding to an integrated luminosity of 137 fb$^{-1}$. The searches for individual WWW, WWZ, WZZ, and ZZZ production are performed in final states with three, four, five, and six leptons (electrons or muons), or with two same-sign leptons plus one or two jets. The observed (expected) significance of the combined VVV production signal is 5.7 (5.9) standard deviations and the corresponding measured cross section relative to the standard model prediction is 1.02 $^{+0.26}_{-0.23}$. The significances of the individual WWW and WWZ production are 3.3 and 3.4 standard deviations, respectively. Measured production cross sections for the individual triboson processes are also reported.
