A Note on T-dualities in the Pure Spinor Heterotic String
(2013-10-22)
In this note we study the preservation of the classical pure spinor BRST constraints under super T-duality transformations. We also determine the invariance of the one-loop conformal invariance and of the local gauge and ...
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 ...
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 ...
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 ...
Pure spinor formalism as an N ≤ 2 topological string
(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 ĉ ≤ 3 N ≤ 2 generators are then constructed where the pure spinor BRST operator ...

Pure spinor partition function and the massive superstring spectrum
(Int School Advanced Studies, 2008-08-01)
We explicitly compute up to the fifth mass-level the partition function of ten-dimensional pure spinor worldsheet variables including the spin dependence. After adding the contribution from the (x(mu), theta(alpha), p(alpha)) ...
