Title: Auxiliary Field Deformations of Sigma Models and T-Duality
Abstract: In this talk, I will explain how to construct an infinite family of classically integrable deformations of the principal chiral model (PCM) using auxiliary fields. This class of theories includes deformations of the PCM by any function of the stress tensor, such as TT and root-TT. An advantage of this formalism is that it facilitates a straightforward analysis of the non-Abelian T-duals of these models, all of which are related to their pre-T-duality cousins by the same canonical transformation, and are thus also classically integrable.
