论文摘要

对于涉及顶级夸克的标准模型(SM)过程,例如顶级夸克 - 易夸克对生产或单个夸克的产生,理论预测取决于SM的基本参数,例如顶级夸克质量。使用ATLA和CMS实验在第二个数据研究期间在CERN LHC收集的大数据样本,可以在具有高精度的实验测量中提取这些参数。此外,可以测量生产过程的特性,例如夸克极化或不对称性。探索了数据集的较大亮度,新的运动学方案和方法,例如顶级夸克具有非常大的横向动量的事件。在这些程序中,提出了最新的SM参数和顶级夸克属性的测量。个人结果还可以用SM的有效现场理论扩展来解释。

For standard model (SM) processes involving top quarks, such as top quark-antiquark pair production or single top quark production, the theoretical predictions depend on fundamental parameters of the SM like the top quark mass. Using the large data sample collected at the CERN LHC in the second data-taking period by the ATLAS and CMS experiments, these parameters can be extracted in experimental measurements with high precision. Furthermore, properties of the production processes such as quark polarization or asymmetries can be measured. Exploiting the large luminosity of the data set, new kinematic regimes and methods are explored, as for events in which the top quarks have a very large transverse momentum. In these proceedings, recent measurements of SM parameters and top quark properties are presented. Individual results are also interpreted in terms of effective field theory extensions of the SM.
