我讨论和审查软反常尺寸QCD描述软胶子阈值重命名的硬散射过程的范围很广。利用截面在矩空间中的因式分解性质和重整化群演化方法，导出了微分剖分截面的一般形式。详细的表达式给出了软异常尺寸在一个，两个，和三个循环，包括一些新的结果，大量的部分子过程涉及顶夸克，电弱玻色子，希格斯玻色子，和其他粒子在标准模型和超越。
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.
