Large N limit of orbifold field theories

Abstract

We consider a certain orbifoldization of the N = 4 field theories that leads to N = 2, 1, 0 field theories in four dimensions. These theories were recently analyzed using the string theory perturbation technique. It was found that in the large N limit all correlation functions of the orbifold theories coincide with those of N = 4, modulo the rescaling of the gauge coupling constant. In this paper we repeat the same analysis using field theoretical language.
