# Dressing cosets and multi-parametric integrable deformations

## TL;DR

This paper introduces a new method for constructing dressing cosets sigma-models using isotropic gauging of E-models, demonstrating that multi-parametric integrable deformations of the principal chiral model are dressing cosets with well-understood dynamics.

## Contribution

It presents a novel construction approach for dressing cosets sigma-models and shows that recent multi-parametric integrable deformations are inherently dressing cosets, ensuring renormalizability and explicit current algebra characterization.

## Key findings

- Multi-parametric deformations are dressing cosets.
- Dressing cosets are automatically renormalizable.
- Dynamics are fully characterized by current algebras.

## Abstract

We provide a new construction of the dressing cosets sigma-models which is based on an isotropic gauging of the E-models. As an application of this new approach, we show that the recently constructed multi-parametric integrable deformations of the principal chiral model are the dressing cosets, they are therefore automatically renormalizable and their dynamics can be completely characterized in terms of current algebras.
