Large-N supersymmetric beta-functions

Abstract

We present calculations of the leading and O(1/N) terms in a large-N expansion of the β-functions for various supersymmetric theories: a Wess-Zumino model, supersymmetric QED and a non-abelian supersymmetric gauge theory. In all cases N is the number of a class of the chiral superfields in the theory.
