NSR String in Ads_3 Backgrounds: Nonlocal Charges

Abstract

We consider NSR superstring in AdS_3 X S_3 X R_4 background. The action is expressed in terms of the variables on the group manifolds SL(2,R) and SU(2) as 1+1 dimensional sigma models with Wess-Zumino terms, associated with AdS_3 and S_3 respectively. R_4 is flat Euclidean space. We show the existence of classical nonlocal conserved currents in the superspace formulation for the nonlinear sigma model with the WZ term in the context of NSR string. We propose Ward identities utilizing the existence of the nonlocal conserved currents.
