Abstract

We compute the symbol of the two-loop five-point scattering amplitude in N=4 supersymmetric Yang-Mills theory, including its full color dependence. This requires constructing the symbol of all two-loop five-point nonplanar massless master integrals, for which we give explicit results.

摘要

我们计算了N = 4超对称杨-米尔斯理论中两圈五点散射振幅的符号，包括其完整的颜色依赖性。这需要构建所有两圈五点非平面无质量主积分的符号，我们给出了明确的结果。
