# A proposal for nonabelian (0,2) mirrors

## TL;DR

This paper proposes a new method for constructing mirrors of (0,2) supersymmetric gauged linear sigma models, extending previous work and unifying abelian and nonabelian cases, especially for models with linear diagonal E terms.

## Contribution

It introduces a systematic construction of (0,2) mirrors for GLSMs with linear diagonal E terms, generalizing and simplifying prior approaches for abelian models.

## Key findings

- Unified mirror construction for (0,2) GLSMs
- Extension of Hori-Vafa and nonabelian mirror prescriptions
- Simplified framework for abelian (0,2) models

## Abstract

In this paper we give a proposal for mirrors to (0,2) supersymmetric gauged linear sigma models (GLSMs), for those (0,2) GLSMs which are deformations of (2,2) GLSMs. Specifically, we propose a construction of (0,2) mirrors for (0,2) GLSMs with E terms that are linear and diagonal, reducing to both the Hori-Vafa prescription as well as a recent (2,2) nonabelian mirrors proposal on the (2,2) locus. For the special case of abelian (0,2) GLSMs, two of the authors have previously proposed a systematic construction, which is both simplified and generalized by the proposal here.
