THE b-FIELD IN PURE SPINOR QUANTIZATION OF SUPERSTRINGS
نویسندگان
چکیده
In the framework of the pure spinor approach of superstring theories, we describe the Y-formalism and use it to compute the picture raised b-field. At the end we discuss briefly the new, non-minimal formalism of Berkovits and the related non-minimal b-field. The new superstring formulation of Berkovits [1]-[5], based on pure spinors, has solved the old problem of quantization of superstrings with manifest super-Poincaré invariance. It can be considered at present as a complete and consistent formulation of superstring theories, alternative to the NSR and GS ones that shares the advantages of these two formulations without Talk given by M.

Y-formalism in Pure Spinor Quantization of Superstrings
We present the Y-formalism in the pure spinor quantization of superstring theory in detail. Even if the ω−λ OPE is not completely free owing to the presence of the projector reflecting the pure spinor constraint, it is shown that one can construct at the quantum level a conformal field theory in full agreement with the Berkovits’ pure spinor formalism. The OPE’s of the two formalisms are the sa...
متن کاملOn the b-antighost in the Pure Spinor Quantization of Superstrings
Recently Berkovits has constructed a picture raised, compound field bB which is used to compute higher loop amplitudes in the pure spinor approach of superstrings. On the other hand, in the twisted and gauge fixed, superembedding approach with n = 2 worldsheet (w.s.) supersymmetry that reproduces the pure spinor formulation, a field b appears quite naturally as the current of one of the two twi...
متن کاملCovariant Quantization of Superstrings Without Pure Spinor Constraints
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 Kac-Moody algebra, which would lead to an anomaly in the BRST charge, is treated as a new generator with a new b − c system. We construct a nilpotent BRST current, an anomalous ghost current and an anomaly-free energy-mo...
متن کاملY-formalism and b ghost in the Non-minimal Pure Spinor Formalism of Superstrings
We present the Y-formalism for the non-minimal pure spinor quantization of superstrings. In the framework of this formalism we compute, at the quantum level, the explicit form of the compound operators involved in the construction of the b ghost, their normalordering contributions and the relevant relations among them. We use these results to construct the quantum-mechanical b ghost in the non-...
متن کاملThe Superembedding Origin of the Berkovits Pure Spinor Covariant Quantization of Superstrings
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. As a consequence, the absence of the worldsheet (super)diffeomorphism ghosts in the pure spinor qu...
