On the Berkovits covariant quantization of the GS superstring”, Phys
 Phys. B 639
"... We study the covariant quantization of the GreenSchwarz (GS) superstrings proposed recently by Berkovits. In particular, we reformulate the Berkovits approach in a way that clarifies its relation with the GS approach and allows to derive in a straightforward way its extension to curved spacetime ba ..."

The Superembedding Origin of the Berkovits Pure Spinor Covariant Quantization of Superstrings
, 2002
"... We show that the pure spinor formalism proposed by Berkovits to covariantly quantize superstrings is a gauge fixed, twisted version of the complexified n = 2 superembedding formulation of the superstring. This provides the Berkovits approach with a geometrical superdiffeomorphism invariant ground. A ..."

Lectures on curved betagamma systems, pure spinors, and anomalies
"... The curved betagamma system is the chiral sector of a certain infinite radius limit of the nonlinear sigma model with complex target space. Naively it only depends on the complex structures on the worldsheet and the target space. It may suffer from the worldsheet and target space diffeomorphism an ..."

anomalies which we review. We analyze the curved betagamma system on the space of pure spinors, aiming to verify the consistency of Berkovits covariant superstring quantization. We demonstrate that under certain conditions both anomalies can be cancelled for the pure spinor sigma model, in which case one
YangMills Theory as an Illustration of the Covariant Quantization of Superstrings
, 2002
"... We present a new approach to the quantization of the superstring. After a brief review of the classical GreenSchwarz formulation for the superstring and Berkovits ’ approach to its quantization based on pure spinors, we discuss our formulation without pure spinor constraints. In order to illustrate ..."

On the Covariant Quantization of Type II Superstrings
, 2004
"... In a series of papers Grassi, Policastro, Porrati and van Nieuwenhuizen have introduced a new method to covariantly quantize the GSsuperstring by constructing a resolution of the pure spinor constraint of Berkovits ’ approach. Their latest version is based on a gauged WZNW model and a definition of ..."

Dbrane dynamics in constant RamondRamond potentials and noncommutative geometry,” arXiv:hepth/0209164. 31
, 1982
"... Abstract: We study the physics of D–branes in the presence of constant Ramond–Ramond potentials. We first develop a general formalism to analyze open strings in gauge trivial closed string backgrounds, and then apply it both to the RNS string and within Berkovits ’ covariant formalism, where the res ..."

Covariant Matrix Model of Superparticle in the Pure Spinor Formalism
, 2003
"... On the basis of the Berkovits pure spinor formalism of covariant quantization of supermembrane, we attempt to construct a M(atrix) theory which is covariant under SO(1,10) Lorentz group. We first construct a bosonic M(atrix) theory by starting with the firstorder formalism of bosonic membrane, whic ..."

Covariant Quantization of Superstrings Without Pure Spinor Constraints
, 2001
"... We construct a covariant quantum superstring, extending Berkovits ’ approach by introducing new ghosts to relax the pure spinor constraints. The central charge of the underlying KacMoody algebra, which would lead to an anomaly in the BRST charge, is treated as a new generator with a new b − c syste ..."

A covariant action with a constraint and Feynman rules for fermions in open superstring field theory, JHEP 01
, 2005
"... In a way analogous to type IIB supergravity, we give a covariant action for the fermion field supplemented with a constraint which should be imposed on equations of motion, in Berkovits ’ open superstring field theory. From this action we construct Feynman rules for computing perturbative amplitudes ..."

We show how projective superspace appears naturally in the hybrid formulation giving a (partially) geometric interpretation of the harmonic parameter. The lowenergy effective action for ..."
