Wess-Zumino term for AdS superstring

Abstract
We examine a bilinear form Wess-Zumino term for a superstring in anti–de Sitter (AdS) spaces. This is composed of two parts: a bilinear term in superinvariant currents and a total derivative bilinear term which is required for the pseudosuperinvariance of the Wess-Zumino term. The covariant supercharge commutator containing a string charge is also obtained.
