We provide explicit Lagrangian realizations of smooth Renormalization Group flows driven by current bilinears of WZW model Conformal Field Theories. We show how to compute the exact beta-function and operator anomalous dimensions to all orders in the deformation parameters. We provide the exact C-function obeying Zamolodchikov’s c-theorem — the first such example in literature. Our techniques incorporate leading order perturbative results, non-trivial symmetries in the parametric space of these theories as well as gravitational methods.
