GLSMs for non-Kähler geometries
Abstract
We identify a simple mechanism by which H-flux satisfying the modified Bianchi identity arises in garden-variety (0 , 2) gauged linear sigma models. Taking suitable limits leads to effective gauged linear sigma models with Green-Schwarz anomaly cancellation. We test the quantum-consistency of a class of such effective theories by constructing an off-shell superconformal algebra, identifying unexpected topological constraints on the existence of this algebra and providing evidence that these models run to good CFTs in the deep IR when all of the constraints are satisfied.
