Ambitwistor pure spinor string in a type II supergravity background
arXiv:1505.05122
Abstract
We construct the ambitwistor pure spinor string in a general type II supergravity background in the semi-classical regime. Almost all supergravity constraints are obtained from nilpotency of the BRST charge and further consistency conditions from additional world-sheet symmetries. We also discuss the case of background.
