论文摘要
我回顾了三个粒子$ i $，$ j $，$ k $的树级幅度的分解属性。三重线分裂函数既包含迭代的单个未解决的贡献，又包含真正的双重未解决的贡献。我通过根据两粒子分裂功能的产物来重写已知的三重界线拆分功能，并在$ \ {i，j，k \} $的任何两个时都明确有限。
I review the factorisation properties of tree level amplitudes when three particles $i$, $j$, $k$ are collinear. The triple collinear splitting functions contain both iterated single unresolved contributions, and genuine double unresolved contributions. I make this explicit by rewriting the known triple collinear splitting functions for a quark and two gluons in terms of products of two-particle splitting functions, and a remainder that is explicitly finite when any two of $\{i,j,k\}$ are collinear.
