在LHC上用ATLAS和CMS探测器测量顶夸克质量

Measurements of the top quark mass using the ATLAS and CMS detectors at the LHC

Sven Menke

摘要:

本文介绍了在LHC上由ATLAS和CMS实验获得的质心能量为7和8 TeV的顶夸克质量的最新测量结果。顶夸克的质量可以使用多种方法和渠道来测量,包括重建顶夸克的不变质量分布和顶夸克衰变分布的形状。本文还讨论了基于包含性tt-bar截面的测量和基于tt-bar + 1喷流通道中微分截面的新观测量。将各种渠道的结果合并,并与世界平均水平进行比较。

英文摘要:

The latest measurements of the top quark mass obtained by the ATLAS and CMS experiments at the LHC for centre-of-mass energies of 7 and 8 TeV are presented. The mass of the top quark is measured using several methods and channels, including the reconstructed invariant mass distribution of the top quark and shapes of top quark decay distributions. Measurements based on the inclusive tt-bar cross section and novel observables based on the differential cross section in the tt-bar + 1 jet channel are also discussed. The results of the various channels are combined and compared to the world average.
