我们提出了一个形式主义和详细的分析结果软胶子重命名为2\rightarrow n$过程中的单粒子包容(1 PI)运动学。这概括了以前的工作,在1 PI运动学中的$2 \rightarrow 2$过程的再确认。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涉及顶夸克和希格斯玻色子或Z玻色子的过程,我们提供了一些简短的数值结果。
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.
