Multiloop superstring amplitudes from non-minimal pure spinor formalism
(Int School Advanced Studies, 2006-12-01)
Using the non-minimal version of the pure spinor formalism, manifestly super-Poincare covariant superstring scattering amplitudes can be computed as in topological string theory without the need of picture-changing operators. ...
D=10 Super Yang-Mills, D=11 Supergravity and the Pure Spinor Superfield Formalism
(Universidade Estadual Paulista (Unesp), 2016-03-07)
E bem conhecido como descrever as teor´ıas de Super Yang-Mills (SYM) ´ em D = 10 dimens˜oes e Supergravidade (SG) em D = 11 dimens˜oes no superespa¸co e via seus campos componentes. No entanto, uma nova vers˜ao desses ...
Lorentz invariance of the pure spinor BRST cohomology for the superstring
(Elsevier B.V., 2001-08-16)
In a previous Letter. The BRST cohomology in the pure spinor formalism of the superstring was shown to coincide with the light-cone Green-Schwarz spectrum by using an SO(8) parameterization of the pure spinor. In this ...

The overall coefficient of the two-loop superstring amplitude using pure spinors
(2010-08-02)
Using the results recently obtained for computing integrals over (non-minimal) pure spinor superspace, we compute the coefficient of the massless two-loop four-point amplitude from first principles. Contrasting with the ...

A minimalistic pure spinor sigma-model in AdS
(Springer, 2018-07-25)
The b-ghost of the pure spinor formalism in a general curved background is not holomorphic. For such theories, the construction of the string measure requires the knowledge of the action of diffeomorphisms on the BV phase ...
