Abstract

The Wilson loop/amplitude duality for N=4 SYM states that planar n-point MHV amplitudes
arc equivalent to n-gon lightlike Wilson loops. This has been proved analytically for all
n at one loop. At two loops it has been shown numerically up to 6 points. We have
recently computed two-loop corrections to arbitrary n-gon lightlike Wilson loops in N=4
supersymmetric Yang-Mills theory, using efficient numerical methods. If the correspondence
with amplitudes continues to hold, we have thus computed all planar n-point two-loop MHV
amplitudes in the N =4 theory.
