Color dressed unitarity and recursion for Yang-Mills two-loop all-plus amplitudes

Year: 2020

Type: article

Abstract: We present a direct computation of the full color two-loop five-point all-plus Yang-Mills amplitude using four dimensional unitarity and recursion. We present the $SU({N}_{c})$ amplitudes in compact analytic forms. Our results match the explicit expressions previously computed but do not require full two-loop integral methods.
