The Differential of All Two-Loop MHV Amplitudes in N=4 Yang-Mills Theory
John Golden, Marcus Spradlin
We present an explicit analytic calculation of the differential of the planar n-particle, two-loop MHV scattering amplitude in N=4 super Yang-Mills theory. The result is expressed…

Motivic Amplitudes and Cluster Coordinates
John Golden, Alexander B. Goncharov, Marcus Spradlin +2
In this paper we study motivic amplitudes--objects which contain all of the essential mathematical content of scattering amplitudes in planar SYM theory in a completely canonical w…
