The Complete Four-Loop Four-Point Amplitude in N=4 Super-Yang-Mills Theory

We present the complete four-loop four-point amplitude in N=4 super-Yang-Mills theory, for a general gauge group and general D-dimensional covariant kinematics, and including all non-planar contributions. We use the method of maximal cuts --- an efficient application of the unitarity method --- to c...
