We describe the analytic properties of scattering amplitudes in N=4 super Yang-Mills theory, with the focus on high order corrections to the six-particle MHV amplitude. By making an ansatz for the analytic structure and imposing physical constraints, including matching the BFKL expansion in multi-Regge kinematics and the operator product expansion for the dual Wilson loop in the near-collinear regime, we are able to explicitly construct the amplitude to four loops in perturbation theory.
