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.enconformal field models in string theoryanomalies in field and string theoriesSIGMA-MODELOne-loop conformal invariance of the type II pure spinor superstring in a curved backgroundArtículoCC BY 4.0 Atribución/Reconocimiento 4.0 Internacional Deed10.1088/1126-6708/2007/01/042
