从LHC和Tevatron测量顶夸克质量

Measurements of the top quark mass from the LHC and the Tevatron

Oleg Brandt

摘要:

顶夸克的质量是标准模型的一个基本参数,必须通过实验来确定。在这些程序中,我回顾了最近的测量顶夸克质量的$pp$碰撞在$\sqrt s=7,~8,$和13 TeV的ATLAS和CMS探测器记录在大型强子对撞机,并在$p\bar p$碰撞在$\sqrt s=1.96$ TeV的CDF和D0实验记录在Tevatron。测量是在含有两个、一个和没有带电轻子的最终状态下进行的。相对精度可达0.3%。此外,最近的测量,旨在确定顶夸克质量的定义良好的极计划使用包括$t\bar t$和$t\bar t+1~{\rm jet}$生产。

英文摘要:

The mass of the top quark is a fundamental parameter of the standard model and has to be determined experimentally. In these proceedings, I review recent measurements of the top quark mass in $pp$ collisions at $\sqrt s=7,~8,$ and 13 TeV recorded by the ATLAS and CMS detectors at the LHC, and in $p\bar p$ collisions at $\sqrt s=1.96$ TeV recorded by the CDF and D0 experiments at the Tevatron. The measurements are performed in final states containing two, one, and no charged leptons. A relative precision of down to 0.3% is attained. In addition, recent measurements aiming to determine the top quark mass in the well-defined pole scheme using both inclusive $t\bar t$ and $t\bar t+1~{\rm jet}$ production are presented.
