Ítem One-loop conformal invariance of the type II pure spinor superstring in a curved background(Scuola Internazionale Superiore di Studi Avanzati (SISSA) [Associate Organisation] Springer Verlag [Commercial Publisher], 2007-01) Bedoya, O.; Chandia, O.We compute the one-loop beta functions for the Type II superstring using the pure spinor formalism in a generic supergravity background. It is known that the classical pure spinor BRST symmetry puts the background fields on-shell. In this paper we show that the one-loop beta functions vanish as a consequence of the classical BRST symmetry of the action.
