# Ilarion Melnikov : The Coulomb Branch in Gauged Linear Sigma Models

I will present recent work with M.R. Plesser on the GLSM perspective on closed string tachyon condensation in non-supersymmetric orbifolds. These models are distinguished from their supersymmetric relatives by the appearance of weakly coupled Coulomb vacua in certain phases of the GLSM. We study the form of A-twisted correlators in these theories. Using standard techniques, we are able to compute these correlators in a pure Higgs phase (one without Coulomb vacua). These correlators are independent of which phase is used to compute them, and thus we can learn about the properties of the Coulomb branch, where direct computations are difficult.
