WZW-like action for heterotic string field theory
(2004-11-01)
We complete the construction of the Neveu-Schwarz sector of heterotic string field theory begun in [9] by giving a closed-form expression for the action and gauge transformations. Just as the Wess-Zumino-Witten (WZW) action ...

Simplified pure spinor b ghost in a curved heterotic superstring background
(Springer, 2014-06-03)
Using the RNS-like fermionic vector variables introduced in arXiv:1305.0693, the pure spinor b ghost in a curved heterotic superstring background is easily constructed. This construction simplifies and completes the b ghost ...
Relating the b ghost and the vertex operators of the pure spinor superstring
(Springer Science and Business Media Deutschland GmbH, 2021-03)
The OPE between the composite b ghost and the unintegrated vertex operator for massless states of the pure spinor superstring is computed and shown to reproduce the structure of the bosonic string result. The double pole ...
Field theory actions for ambitwistor string and superstring
(Springer, 2018-09-17)
We analyze the free ambitwistor string field theory action for the bosonic string, heterotic string and both GSO sectors of the Type II string. The spectrum contains non-unitary states and provides an interesting consistency ...
A note on the classical BRST symmetry of the pure spinor string in a curved background
(Scuola Internazionale Superiore di Studi Avanzati (SISSA) [Associate Organisation] Springer Verlag [Commercial Publisher], 2006-07)
The classical pure spinor version of the heterotic superstring in a supergravity and super Yang-Mills background is considered. We obtain the BRST transformations of the world-sheet fields. They are consistent with the ...
On the spectrum and spacetime supersymmetry of heterotic ambitwistor string
(Springer, 2019-08-20)
We analyse the BRST cohomology of the Ramond sector of heterotic ambitwistor theory. We also write the free string field theory action and compute the supersymmetry transformations.
Pure spinor formalism as an N=2 topological string
(Int School Advanced Studies, 2005-10-01)
Following suggestions of Nekrasov and Siegel, a non-minimal set of fields are added to the pure spinor formalism for the superstring. Twisted (c) over cap = 3 N = 2 generators are then constructed where the pure spinor ...
