含单粒子运动学中$2\rightarrow n$过程的恢复

Resummation for $2\rightarrow n$ processes in single-particle-inclusive kinematics

Matthew Forslund, Nikolaos Kidonakis

摘要:

本文给出了含单粒子(1PI)运动学中$2\rightarrow n$过程的软胶子再活化的形式和详细的分析结果。这概括了以前的工作,在1PI运动学的$2 \rightarrow 2$过程中的再确认。我们还提出了软异常尺寸在一个和两个循环的某些$2 \rightarrow 3$过程涉及顶夸克和希格斯或$Z$玻色子,我们提供了一些简短的数值结果。

英文摘要:

We present a formalism and detailed analytical results for soft-gluon resummation for $2\rightarrow n$ processes in single-particle-inclusive (1PI) kinematics. This generalizes previous work on resummation for $2 \rightarrow 2$ processes in 1PI kinematics. We also present soft anomalous dimensions at one and two loops for certain $2 \rightarrow 3$ processes involving top quarks and Higgs or $Z$ bosons, and we provide some brief numerical results.
