CFT for Closed String Tachyon Condensation

We construct a class of CFTs which describe space-dependent closed string tachyon backgrounds as the IR limit of GLSMs in which the FI-parameter is promoted to a superfield. The entire process of tachyon condensation is described by a single CFT. We apply this construction to several examples, in which the target space is deformed drastically, and the dilaton background may vary, as a tachyon condenses.
