Query: Non-minimal fields of the pure spinor string in general curved
  backgrounds   We study the coupling of the non-minimal ghost fields of the pure spinor
superstring in general curved backgrounds. The coupling is found solving the
consistent relations from the nilpotency of the non-minimal BRST charge.
