Integrable auxiliary field sigma model and the metric approach to $T\bar{T}$-like deformations

We describe a family of two-dimensional metric deformations that preserve integrability. The seeds are (classically) conformal integrable field theories and the deformations are directly related to different classes of auxiliary field sigma models. We introduce a master action connecting deformations by Lie-algebra-val...
