A new proposal for the picture changing operators in the minimal pure spinor formalism
(SPRINGER, 2011)
Using a new proposal for the ""picture lowering"" operators, we compute the tree level scattering amplitude in the minimal pure spinor formalism by performing the integration over the pure spinor space as a multidimensional ...

One-loop conformal invariance of the type II pure spinor superstring in a curved background
(Scuola Internazionale Superiore di Studi Avanzati (SISSA) [Associate Organisation] Springer Verlag [Commercial Publisher], 2007-01)
We compute the one-loop beta functions for the Type II superstring using the pure spinor formalism in a generic supergravity background. It is known that the classical pure spinor BRST symmetry puts the background fields ...
Notes on beta-deformations of the pure spinor superstring in AdS(5) x S(5)
(ELSEVIER SCIENCE BV, 2011)
We study the properties of the vertex operator for the beta-deformation of the superstring in AdS(5) x S(5) in the pure spinor formalism. We discuss the action of supersymmetry on the infinitesimal beta-deformation, the ...
Some superstring amplitude computations with the non-minimal pure spinor formalism
(Int School Advanced Studies, 2006-11-01)
We use the non-minimal pure spinor formalism to compute in a super-Poincare covariant manner the four-point massless one and two-loop open superstring amplitudes, and the gauge anomaly of the six-point one-loop amplitude. ...

Cohomology in the pure spinor formalism for the superstring
(2000-12-01)
A manifestly super-Poincaré covariant formalism for the superstring has recently been constructed using a pure spinor variable. Unlike the covariant Green-Schwarz formalism, this new formalism is easily quantized with a ...
