Notes on beta-deformations of the pure spinor superstring in AdS(5) x S-5
(Elsevier B.V., 2014)
Simplified D = 11 pure spinor b ghost
(2017-07-01)
A b-ghost was constructed for the D = 11 non-minimal pure spinor superparticle by requiring that (Q, b) = T where Q= Λ αDα+ RαW¯ α is the usual non-minimal pure spinor BRST operator. As was done for the D = 10 b-ghost, we ...
Simplified pure spinor b ghost in a curved heterotic superstring background.
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 ...
The non-minimal heterotic pure spinor string in a curved background.
We study the non-minimal pure spinor string in a curved background. We find that the minimal BRST invariance implies the existence of a non-trivial stress-energy tensor for the minimal and non-minimal variables in the ...
On-shell type II supergravity from the ambitwistor pure spinor string
(2016)
We obtain all the type II supergravity constraints in the pure spinor ambit-wistor string by imposing consistency of local worldsheet gauge symmetries.
Supertwistor description of the AdS pure spinor string
(2016)
We describe the pure spinor string in the AdS(5) x S-5 using unconstrained matrices first used by Roiban and Siegel for the Green-Schwarz superstring.
Master symmetry in the AdS5×S5 pure spinor string
(2017)
We lift the set of classical non-local symmetries recently studied by Klose, Loebbert, and M¨unkler in the context of Z2 cosets to the pure spinor description of the superstring in the AdS5 × S 5 background.
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 consistency relations from the nilpotency of the non-minimal BRST charge.
Master symmetry in the AdS(5) x S-5 pure spinor string.
We lift the set of classical non-local symmetries recently studied by Klose, Loebbert, and Münkler in the context of ℤ 2 cosets to the pure spinor description of the superstring in the AdS 5 × S 5 background.
C ambitwistor pure spinor string in a type II supergravity background.
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 ...
