N=1* model superpotential revisited (IR behaviour of N=4 limit)

TL;DR

This paper revisits the superpotential in N=1 supersymmetric Yang-Mills theory, analyzing the IR behavior of the N=4 limit through elementary field theory and matrix model approaches, focusing on one-loop contributions.

Contribution

It provides a new perspective on the IR behavior of N=4 supersymmetric Yang-Mills theory by connecting superpotential calculations with renormalization group analysis.

Findings

One-loop superpotential contributions are explicitly calculated.

The IR limit of N=4 supersymmetric Yang-Mills is characterized.

Connections between field theory and matrix model approaches are clarified.

Abstract

The one-loop contribution to the superpotential, in particular the Veneziano-Yankielowicz potential in N=1 supersymmetric Yang-Mills model is discussed from an elementary field theory method and the matrix model point of view. Both approaches are based on the Renormalization Group variation of the superconformal N=4 supersymmetric Yang-Mills model.
