在LHC上测量顶夸克质量

Top-quark mass measurements at the LHC

Stijn Blyweert

摘要:

顶夸克质量mt是粒子物理标准模型的基本参数之一。CDF和D 0合作已经对mt进行了非常精确的测量。由于ATLAS和CMS合作已经有了非常大的顶夸克对样本可供分析,他们正在产生越来越精确的结果。最新的测量MT的ATLAS和CMS的概述,使用高达4.7 fb-1的数据在不同的ttbar衰减通道。测量的顶夸克和反顶夸克之间的质量差也显示。最后,单独测量的MT值的组合进行了讨论,连同展望未来MT测量。

英文摘要:

The top-quark mass mt is one of the fundamental parameters of the standard model (SM) of particle physics. The CDF and D0 collaborations already performed very precise measurements of mt . Since the ATLAS and CMS collaborations already have a very large sample of top quark pairs available for analysis, they are producing results with increasing precision. An overview of the most recent measurements of mt by ATLAS and CMS is given, using up to 4.7 fb-1 of data in different ttbar decay channels. The measurement of the mass difference between top and antitop quarks is also shown. Finally, the combination of the individually measured mt values is discussed, together with an outlook for future mt measurements.
