顶夸克的产生、衰变和性质的测量

Measurements of the Production, Decay and Properties of the Top Quark: A Review

Kevin Lannon, Fabrizio Margaroli, Chris Neu

摘要:

有了完整的Tevatron运行II和早期LHC数据样本,进一步了解顶夸克性质的机会从未如此有希望。虽然目前对顶夸克的了解主要来自Tevatron测量,但LHC的实验准备在前所未有的情况下探测顶夸克的产生和衰变。虽然目前还没有顶夸克的测量结果与标准模型的预测相矛盾,但大多数测量结果的精度在统计上仍然有限。此外,一些测量,最值得注意的是顶夸克对产生的前后不对称性,显示出超越标准模型动力学的诱人暗示。顶夸克样本在大型强子对撞机上迅速增长,初步结果现已公布。本文从寻找新物理学证据的角度,对顶夸克测量的现状进行了综述,包括直接寻找标准模型以外的现象,或间接通过精确测量标准模型顶夸克性质。

英文摘要:

With the full Tevatron Run II and early LHC data samples, the opportunity for furthering our understanding of the properties of the top quark has never been more promising. Although the current knowledge of the top quark comes largely from Tevatron measurements, the experiments at the LHC are poised to probe top-quark production and decay in unprecedented regimes. Although no current top quark measurements conclusively contradict predictions from the standard model, the precision of most measurements remains statistically limited. Additionally, some measurements, most notably the forward-backward asymmetry in top quark pair production, show tantalizing hints of beyond-the-Standard-Model dynamics. The top quark sample is growing rapidly at the LHC, with initial results now public. This review examines the current status of top quark measurements in the particular light of searching for evidence of new physics, either through direct searches for beyond the standard model phenomena or indirectly via precise measurements of standard model top quark properties.
