Asymmetric Gepner models in type II

Abstract

We describe new four-dimensional type II compactifications with N = 2 supersymmetry, based on asymmetric Gepner models for K3 × T2. In more than half of these models, all the K3 moduli are lifted, giving at low energies N = 2 supergravity with the STU vector multiplets and no hypermultiplets.©The Authors.
