B-field in AdS(3)/CFT(2) Correspondence and Integrability    [PDF]

Alessandra Cagnazzo, Konstantin Zarembo

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.
