Abstract

We propose an action for a sine-Gordon-like theory, which reproduces the classical equations of motion of the Green-Schwarz-Metsaev-Tseytlin superstring on AdS5 × S5. The action is relativistically invariant. It is a mass-deformed gauged WZW model for SO(4, 1) × SO(5)/SO(4) × SO(4) interacting with fermions.
