Mirror symmetry for the Kazama-Suzuki models

Abstract

We study the $N=2$ coset models in their formulation as supersymmetric gauged Wess-Zumino-Witten models. A model based on the coset $G/H$ is invariant under a symmetry group isomorphic to ${\mathbb{Z}}_{k+Q}$, where $k$ is the level of the model and $Q$ is the dual Coxeter number of $G$. Using a duality-like relationship, we show that the ${\mathbb{Z}}_m$ orbifold of the vectorially gauged model and the ${\mathbb{Z}}_{\tilde{m}}$ orbifold of the axially gauged model are each others mirror partners when $m\tilde{m}=k+Q$.
