Integrable double deformation of the principal chiral model

arXiv:1410.8066 · doi:10.1016/j.nuclphysb.2014.12.018

Abstract

We define a two-parameter family of integrable deformations of the principal chiral model on an arbitrary compact group. The Yang-Baxter sigma-model and the principal chiral model with a Wess-Zumino term both correspond to limits in which one of the two parameters vanishes.
