# Vanishing Next-to-Leading Corrections to the β-Function of the SUSY CPN−1 Model in Three Dimensions

@article{Inami2000VanishingNC, title={Vanishing Next-to-Leading Corrections to the $\beta$-Function of the SUSY CPN−1 Model in Three Dimensions}, author={Takeo Inami and Yorinori Saito and Masayoshi Yamamoto}, journal={Progress of Theoretical Physics}, year={2000}, volume={103}, pages={1283-1288} }

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. 1. Introduction The supersymmetric CP N −1 sigma model in low dimensions has many interesting features. In two dimensions this model shares a few physical properties with supersymmetric gauge theories in four dimensions. 1), 2) Namely, perturbatively…

In this paper, we study the noncommutative supersymmetric CP(N−1) model in 2 + 1 dimensions, where the basic field is in the fundamental representation which, differently to the adjoint…

### Superfield formalism for the one loop effective action and CP(N) model in three dimensions

To obtain the one loop effective action for a given superfield theory, one encounters the notion such as the `supertrace' of a differential operator on superspace. We develop, in a systematic way for…

A closed form of the action of the supersymmetric CP N sigma model on noncommutative superspace in four dimensions is constructed and it is shown that this model has N = 1/2 supersymmetry and that the transformation law is not modified.
