Notes on the ambitwistor pure spinor string

Year: 2016

Type: article

Abstract: 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.
