顶夸克产生中的软胶子修正

Soft-gluon corrections in top-quark production

Nikolaos Kidonakis

摘要:

我回顾了强子碰撞中顶夸克产生的软胶子修正的计算。我描述了理论形式主义,他们的remation和有限阶扩展。我表明,软胶子修正是占主导地位的大量顶夸克过程。我讨论顶-反顶对生产以及单顶生产,包括总截面和微分分布,并与LHC和Tevatron的数据进行比较。我还讨论了顶夸克的产生与带电的希格斯玻色子,$Z$玻色子和其他新物理模型中的粒子。

英文摘要:

I review calculations of soft-gluon corrections for top-quark production in hadron collisions. I describe theoretical formalisms for their resummation and for finite-order expansions. I show that soft-gluon corrections are dominant for a large number of top-quark processes. I discuss top-antitop pair production as well as single-top production, including total cross sections and differential distributions, and compare with data from the LHC and the Tevatron. I also discuss top-quark production in association with charged Higgs bosons, $Z$ bosons, and other particles in models of new physics.
