Planar Abelian Mirror Duals of $\mathcal{N}=2$ SQCD$_3$

TL;DR

This paper introduces a new Abelian mirror dual for three-dimensional $ ext{SQCD}_3$ with $ ext{N}=2$ supersymmetry, derived from $ ext{N}=4$ dual pairs, and validates it through multiple checks.

Contribution

It presents the first proposed Abelian mirror dual for $ ext{N}=2$ SQCD$_3$, extending known dualities via real mass deformation and comprehensive matching.

Findings

Superconformal index matches between duals

$ ext{S}^3_b$ partition functions agree

Moduli spaces and operator maps are consistent

Abstract

We propose an Abelian mirror dual for the $\mathcal{N}=2$ SQCD$_3$ that we obtain as real mass deformation of known $\mathcal{N}=4$ mirror pairs. We match the superconformal index and the $\mathbf{S}^3_b$ partition function, discuss the agreement of the moduli spaces, and provide a map of the gauge invariant operators and the global symmetries as evidence of this duality.
