چکیده
|
In this work, some aspects of the ambitwistor pure spinor string are investigated. the b ghost is presented and its main properties are derived in a simple way, very similar to the usual pure spinor b ghost construction. the heterotic case is also addressed with a new proposal for the brst charge. the brst cohomology is shown to correctly describe the heterotic supergravity spectrum and a semi-composite b ghost is constructed.
