Universal 1-loop divergences for integrable sigma models

Universal 1-loop divergences for integrable sigma models

Abstract We present a simple, new method for the 1-loop renormalization of integrable σ-models. By treating equations of motion and Bianchi identities on an equal footing, we derive ‘universal’ formulae for the 1-loop on-shell divergences, generalizing case-by-case computations in the literature.
