Yang-Mills Theory as an Illustration of the Covariant Quantization of Superstrings
P. A. Grassi, G. Policastro, P. van Nieuwehuizen
We present a new approach to the quantization of the superstring. After a brief review of the classical Green-Schwarz formulation for the superstring and Berkovits' approach to its…
The Covariant Quantum Superstring and Superparticle from their Classical Actions
P. A. Grassi, G. Policastro, P. van Nieuwenhuizen
We develop an approach based on the Noether method to construct nilpotent BRST charges and BRST-invariant actions. We apply this approach first to the holomorphic part of the flat-…
On the BRST Cohomology of Superstrings with/without Pure Spinors
P. A. Grassi, G. Policastro, P. van Nieuwenhuizen
We replace our earlier condition that physical states of the superstring have non-negative grading by the requirement that they are analytic in a new real commuting constant t whic…
The Massless Spectrum of Covariant Superstrings
P. A. Grassi, G. Policastro, P. van Nieuwenhuizen
We obtain the correct cohomology at any ghost number for the open and closed covariant superstring, quantized by an approach which we recently developed. We define physical states…
