摘要：

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.
