Vanishing Next-to-Leading Corrections to the β-Function of the SUSY CP^{N-1} Model in Three Dimensions

Abstract

We study the ultraviolet properties of the supersymmetric CP^{N-1} sigma model in three dimensions to next-to-leading order in the 1/N expansion. We calculate the β-function to this order and verify that it has no next-to-leading order corrections.
