Wess-Zumino-Witten model off criticality

Abstract

We study the renormalization group flow properties of the Wess-Zumino-Witten model in the region of couplings between $g^2=0$ and $g^2=4\pi /k$, by evaluating the two-loop Zamolodchikov's $c$-function. We also discuss the region of negative couplings.
