Joseph Minahan has the best introduction to N=4 super-Yang-Mills that I’ve seen.

Slides from Marcus Spradlin at KITP touch on many developments.

Luis Alday reviews the interpretation of scattering amplitudes at strong coupling as a minimal surface in anti-de-Sitter space.

I believe Simon Caron-Huot’s latest is currently the most advanced paper on the subject: a generalization of scattering amplitudes is proposed, that would possess superconformal and dual superconformal symmetry, and which would begin to explain the simplicity recently discovered in the BDS remainder function, as discussed by Spradlin.
