dc.description.abstractThe pure spinor heterotic string in a generic super Yang-Mills and supergravity background is onsidered. We determine the one-loop BRST anomaly at the cohomological level. We prove that it can be absorbed by consistent corrections of the classical constraints due to Berkovits and Howe, in agreement with the Green-Schwarz cancelation mechanism.en
