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…
Star Integrals, Convolutions and Simplices
Dhritiman Nandan, Miguel F. Paulos, Marcus Spradlin +1
We explore single and multi-loop conformal integrals, such as the ones appearing in dual conformal theories in flat space. Using Mellin amplitudes, a large class of higher loop int…
