ATLAS实验中双玻色子过程的最新观测

Recent observation and measurements of diboson processes from the ATLAS experiment

Yee Chinn Yap

摘要:

本综述涵盖了截至2020年4月已发表或提交发表的ATLAS实验中质量中心能量为$\sqrt{s}=13$ TeV的结果。它总结了玻色子对的包容性生产截面测量结果和与两个喷流相关联的双玻色子的电弱生产。这些测量要么使用ATLAS探测器在2015年至2018年期间在LHC收集的139个$\text{fb}^\text{-1}$的完整积分亮度,要么使用36个$\text{fb}^\text{-1}$的部分数据集。对双玻色子的包容产生率进行了高精度的研究。这些测量为标准模型的电弱部分提供了严格的测试,并允许通过反常的三次和四次规范玻色子耦合来寻找新的物理。

英文摘要:

This review covers results at a centre-of-mass energy of $\sqrt{s}=13$ TeV from the ATLAS experiment that have been published, or submitted for publication, up to April 2020. It summarizes results on the inclusive production cross-section measurements of boson pairs and of the electroweak production of diboson in association with two jets. The measurements either use the full integrated luminosity of 139 $\text{fb}^\text{-1}$ collected by the ATLAS detector at the LHC from 2015 to 2018, or a partial dataset of 36 $\text{fb}^\text{-1}$. The inclusive production rates of diboson are studied to high precision. These measurements provide stringent tests of the electroweak sector of the Standard Model and allow search for new physics via anomalous triple and quartic gauge boson couplings.
