They are characterized by the integer level k of the current algebra, a deformation parameter \u03bb and they exhibit a remarkable invariance involving the inversion of \u03bb . We compute the \u03b2 -function for \u03bb to leading order in 1k . Based on agreement with previous results for the exact \u03b2 -function of the non-Abelian bosonized Thirring model and matching global symmetries, we state that our integrable models are the resummed version (capturing all counterterms in perturbation theory) of the non-Abelian bosonized Thirring model for a simple group G . Finally, we present an analogous treatment in a simple example of a closely related class of models interpolating between gauged WZW coset CFTs and the non-Abelian T-duals of PCM for the coset G/H ."
