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 ...
Relating the Green-Schwarz and pure spinor formalisms for the superstring
(2005-01-01)
Although it is not known how to covariantly quantize the Green-Schwarz (GS) superstring, there exists a semi-light-cone gauge choice in which the GS superstring can be quantized in a conformally invariant manner. In this ...

Supersymmetry breaking effects using the pure spinor formalism of the superstring
(Springer, 2014-06-23)
The SO(32) heterotic superstring on a Calabi-Yau manifold can spontaneously break supersymmetry at one-loop order even when it is unbroken at tree-level. It is known that calculating the supersymmetry-breaking effects in ...
A simpler prescription for MHV graviton tree amplitudes in superstring theory
(Springer, 2013-11-05)
We extend the Berkovits-Maldacena prescription for MHV amplitudes of the open superstring to the closed superstring, showing that in the alpha'aEuro parts per thousand= 0 limit it reduces to the result of supergravity found ...
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 ...
