New Theories With Quantum Modified Moduli Space

TL;DR

This paper extends the study of Kutasov-type duals in supersymmetric gauge theories to cases with fewer flavors, revealing superconformal regions and modifications to the magnetic superpotential, thus broadening the understanding of quantum-modified moduli spaces.

Contribution

It introduces a new analysis of Kutasov-type duals with fewer flavors, showing superconformal regions and the need for additional instanton-generated superpotential terms.

Findings

Parts of the moduli space become superconformal.

The magnetic superpotential requires an additional instanton-generated term for SU(2).

Generalizes quantum-modified moduli space in dual theories.

Abstract

Kutasov--type duals of supersymmetric gauge theories had been studied only in the dual regime and the s-confining case. Here we extend the discussion to the case of less flavor, analogous to the case of quantum-modified moduli space in Seiberg duality. Unlike the Seiberg duality, however, we find that parts of the moduli space become superconformal, generalizing the so far isolated example of SU(2) theory with two doublets and a triplet. We also point out that the magnetic superpotential needs to be augmented by an additional instanton-generated piece when the magnetic group is SU(2).
