Worldsheet Supersymmetry in Pohlmeyer-Reduced Superstrings

摘要

We show that the AdS_3 × S~3 and AdS_5 × S~5 superstring theories in the Pohlmeyer-reduced form reveal hidden N = (4,4) and N = (8,8) worldsheet supersymmetries. The characteristic feature of these transformations is the presence of non-local terms.
