Abstract

We construct topological Wess-Zumino term for supercoset sigma-models on various AdS 3 backgrounds. For appropriately chosen set of parameters, the sigma-model remains integrable when the Wess-Zumino term is added to the action. Moreover, the conditions for integrability, kappa-symmetry and conformal invariance are equivalent to each other.
