Description
We verify the supersymmetric O(N+1) exact S-matrix beyond leading order in the large N expansion, by calculating the t-channel amplitudes of the corresponding field theory. The expansion is carried out in terms of the natural parameter N-1, rather than N+1. The renormalization of the model and its relation to the scattering elements is also discussed. (orig.)
