On the Berkovits Covariant Quantization of GS Superstring
arXiv:hep-th/0109051 · doi:10.1016/S0370-2693(01)01131-5
Abstract
We study the covariant quantization of the Green-Schwarz (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 background. We explain the procedure working explicitly in the case of the heterotic string.
