The Non-minimal Heterotic Pure Spinor String in a Curved Background

Published 27 Nov 2013 in hep-th | (1311.7012v3)

Abstract: We study the non-minimal pure spinor string in a curved background. We find that the minimal BRST invariance implies the existence of a non-trivial stress-energy tensor for the minimal and non-minimal variables in the heterotic curved background. We find constraint equations for the b ghost. We construct the b ghost as a solution of these constraints.
