摘要

本文综述了在欧洲核子研究中心的大型强子对撞机上，ATLAS合作使用质子-质子对撞得到的二玻色子和多玻色子产生的横截面结果。本文重点讨论了$ $ZZ$、$ $W^±Z$、$W^+W^-$在$\sqrt{s}$=13 TeV时的产生，$W^+W^-$和$W^±Z$在8 TeV时半光子末态的产生和$W^±Z$在8 TeV时的产生。并简要讨论了从这些测量中得到的异常三重和四次规范玻色子耦合的约束。目前发现实测截面在估计的不确定度范围内与标准模型预测一致。

Latest results on diboson and multiboson production from ATLAS experiment

These proceedings are presenting an overview of the diboson and multiboson production cross-section results obtained by the ATLAS collaboration using proton-proton collisions at the LHC at CERN. The note is focused on the latest measurements of $ZZ$, $W^±Z$, $W^+W^-$ production at $\sqrt{s}$=13 TeV, of $W^+W^-$ and $W^±Z$ production in the semileptonic ﬁnal state at 8 TeV and of triboson production at 8 TeV. Constraints on anomalous triple and quartic gauge boson couplings obtained from these measurements are briefly discussed as well. At present the measured cross sections are found to be in agreement with the Standard Model predictions within the estimated uncertainties.
