Two-Loop Five-Point Amplitude in N=4 Super-Yang-Mills Theory

Phys Rev Lett. 2019 Mar 29;122(12):121603. doi: 10.1103/PhysRevLett.122.121603.

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.
