The Coulomb Branch in Gauged Linear Sigma Models

Abstract

We investigate toric GLSMs as models for tachyon condensation in type II strings on space-time non-supersymmetric orbifold singularities. The A-model correlators in these theories satisfy a set of relations related to the topology of the resolved orbifold. Using these relations we compute the correlators and find a non-trivial chiral ring in the IR, which we interpret as supported on isolated Coulomb vacua of the theory.

34 pages, 5 figures with xy-pic. Several errors corrected. Conjectured form for the correlators now agrees with all tested cases
