论文摘要

我在QCD中讨论并回顾了软性异常的尺寸,这些尺寸描述了软性脱落阈值的重新召集,以实现广泛的硬质量过程。实现了瞬间空间中横截面的分解特性,并实现了重新归一化组的进化,以得出差分重新介绍的横截面的一般形式。为一个,两个和三个循环(包括一些新的结果)提供了详细的表达式,用于大量涉及顶级夸克,电动玻色子,higgs玻色子和标准模型中其他粒子的党派过程。

I discuss and review soft anomalous dimensions in QCD that describe soft-gluon threshold resummation for a wide range of hard-scattering processes. The factorization properties of the cross section in moment space and renormalization-group evolution are implemented to derive a general form for differential resummed cross sections. Detailed expressions are given for the soft anomalous dimensions at one, two, and three loops, including some new results, for a large number of partonic processes involving top quarks, electroweak bosons, Higgs bosons, and other particles in the Standard Model and beyond.
