Symmetries of the N = 4 SYM S - matrix

Abstract

Under the assumption of a CSW generalization to loop amplitudes in N = 4 SYM, 1. We prove that, formally the S-matrix is superconformal invariant to any loop order, and 2. We argue that superconformal symmetry survives regularization. More precisely, IR safe quantities constructed from the S-matrix are superconformal covariant. The IR divergences are… (More)
