Abstract

By employing the perturbiner method, we study the tree- and one-loop-level amplitudes in (anti)self-dual Yang-Mills, focusing on color-kinematics duality and double copy features; they arise naturally even in the fully off-shell case. In particular, we calculate the respective the Kawai-Lewellen-Tye relations for tree-level Berends-Giele currents and color-kinematics master numerators at one loop, both cases for any number of external particles.

杨-米尔斯和引力理论（反）自对偶扇区的树级和单环级双复制

采用摄动器方法研究了（反）自对偶Yang-Mills的树级和单环级幅值，重点研究了颜色-运动学对偶性和双复制特征；即使在完全脱壳的情况下，它们也会自然产生。特别地，我们计算了树级Berends-Giele电流和颜色运动主分子在一个环路上的kawai - lewellen - type关系，这两种情况都适用于任意数量的外部粒子。2025年由美国物理学会出版
