摘要

在平面$\mathcal{N} = 4$超对称Yang-Mills理论中，我们引入了一种新的方法来执行多regge -运动学的高阶计算，并将现有的分解方法推广到两个环上的所有环阶的构造块。之后，我们将解释如何使用这个框架来轻松地从现有的振幅中获得更高的环路振幅，以及如何将它们与具有更高数量的腿的振幅联系起来。

Multi-Loop Amplitudes in the High-Energy Limit in N = 4 SYM

We introduce a novel way to perform high-order computations in multi-Regge-kinematics in planar $\mathcal{N} = 4$ supersymmetric Yang-Mills theory and generalize the existing factorization into building blocks at two loops to all loop orders. Afterwards, we will explain how this framework can be used to easily obtain higher-loop amplitudes from existing amplitudes and how to relate them to amplitudes with higher number of legs.
