Description
I will describe joint work with D. Israël and I. Melnikov on (0,2) gauged linear sigma models relevant for heterotic flux compactifications. An important class of flux backgrounds is realized as a torus fibration over K3 with a stable holomorphic vector bundle. I will present torsional GLSMs whose large radius phase describes such a geometry with a trivial gauge bundle, and which admit a Landau–Ginzburg orbifold phase. I will also discuss related (0,2) constructions for Calabi–Yau compactifications with line bundles.
