Worldsheet supersymmetry in Pohlmeyer-reduced superstrings

Abstract

We show that the AdS3 × S3 and AdS5 × S5 superstring theories in the Pohlmeyer-reduced form reveal hidden script N = (4, 4) and script N = (8, 8) worldsheet supersymmetries. The characteristic feature of these transformations is the presence of non-local terms.
