论文摘要
我们研究了库仑分支上n = 4 Sym中五点W玻色子散射幅度的结构。我们表明，最多两个循环IR差异指数，并由$γ_{OCT} $异常尺寸控制，类似于文献中最近考虑的四点振幅案例。我们还对五点振幅的全环结构做出了猜想
We investigate the structure of the five-point W boson scattering amplitude in N=4 SYM on the Coulomb branch in a small mass limit. We show that up to two loops the IR divergences exponentiate and are controlled by the $Γ_{oct}$ anomalous dimension similar to the four-point amplitude case considered recently in the literature. We also make a conjecture regarding the all-loop structure of the five-point amplitude
