标题： Three-loop soft anomalous dimensions for top-quark production

摘要： 我通过三个环路给出了控制涉及顶夸克过程中的软胶子发射的软异常维数的结果。 特别是 我给出了单顶夸克产生和顶夸克对产生通道以及包含新物理的过程的结果，包括 $tZ$， $tZ'$， $t \gamma$和 $tH^-$ 的产生。 这些计算是达到 N$^3$LL 精度的重求和的组成部分以及 N$^3$LO 软胶子修正的推导的组成部分。 显示英文摘要

摘要： I present results through three loops for soft anomalous dimensions that control soft-gluon emission in processes involving the top quark. In particular I present results for channels in single-top production and top-pair production as well as for processes with new physics, including $tZ$, $tZ'$, $t \gamma$, and $tH^-$ production. These calculations are ingredients to resummations at N$^3$LL accuracy and to derivations of N$^3$LO soft-gluon corrections.
