7 Jul 2003 | | Journal: | Nucl.Phys. B676 (2004) 43-63 | | Subject: | hep-th | | Affiliation: | YITP, Stony Brook), G. Policastro (DAMTP, Cambridge), and P. van Nieuwenhuizen (YITP, Stony Brook | | Abstract: | We present a new development in our approach to the covariant quantization of superstrings in 10 dimensions which is based on a gauged WZNW model. To incorporate worldsheet diffeomorphisms we need the quartet of ghosts $(b_{zz},c^{z}, _{zz}, g^{z})$ for topological gravity. The currents of this combined system form an N=2 superconformal algebra. The model has vanishing central charge and contains two anticommuting BRST charges, $Q_{S}=Q_{W} + oint g^{z} b_{zz} + oint eta_{z}$ and $Q_{V} = oint c^{z} Big(T^{W}_{zz} + {1over 2} T^{top}_{zz}Big) + g^{z} (B^{W}_{zz} + {1over 2} B^{top}_{zz} Big)$, where $eta_{z}$ is obtained by the usual fermionization of $_{zz}, g^{z}$. Physical states form the cohomology of $Q_{S}+Q_{V}$, have nonnegative grading, and are annihilated by $b_{0}$ and $eta_{0}$. We no longer introduce any ghosts by hand, and the formalism is completely Lorentz covariant. | | Source: | arXiv, hep-th/0307056 | | Services: | Forum | Review | PDF | Favorites | |
