A Note on Renormalization Group Invariance And Exact Results in SUSY Gauge Theories

TL;DR

This paper discusses the renormalization group invariance in supersymmetric gauge theories, clarifying misconceptions about the dynamical scale's renormalization and emphasizing the stability of exact results.

Contribution

It provides a clarification on the non-renormalization of the dynamical scale in SUSY theories, resolving a recent puzzle in the field.

Findings

Renormalization of the dynamical scale mbda does not occur.

Exact results in SUSY gauge theories are RG invariant.

Clarifies misconceptions in recent literature.

Abstract

We comment on a recent puzzle regarding renormalization group invariance of exact results in SUSY theories, and argue that a purported renormalization of the dynamical scale \Lambda does not in fact occur.
