Proof of ultra-violet finiteness for a planar non-supersymmetric Yang-Mills theory

Abstract

This paper focuses on a three-parameter deformation of N=4 Yang-Mills that breaks all the supersymmetry in the theory. We show that the resulting non-supersymmetric gauge theory is scale invariant, in the planar approximation, by proving that its Green functions are ultra-violet finite to all orders in light-cone perturbation theory.Comment: 13 pages, 1 figure; v2: minor correction
