Vanishing Next-to-Leading Corrections to the β-Function of the SUSY CPN-1 Model in Three Dimensions
Takeo Inami, Yorinori Saito, Masayoshi Yamamoto
Abstract
We study the ultraviolet properties of the supersymmetric CPN-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.
