N=4 Superconformal Symmetry for the Covariant Quantum Superstring | | P.A. Grassi

2 Aug 2004 | | Journal: | Phys.Lett. B610 (2005) 129-140 | | Subject: | hep-th | | Affiliation: | DISTA, Univ. Piem Orien., YITP Stony Brook) and P. van Nieuwenhuizen (YITP, Stony Brook | | Abstract: | We extend our formulation of the covariant quantum superstring as a WZNW model with N=2 superconformal symmetry to N=4. The two anticommuting BRST charges in the N=4 multiplet of charges are the usual BRST charge Q_S and a charge Q_V proposed by Dijkgraaf, Verlinde and Verlinde for topological models. Using our recent work on "gauging cosets", we then construct a further charge Q_C which anticommutes with Q_S + Q_V and which is intended for the definition of the physical spectrum. | | Source: | arXiv, hep-th/0408007 | | Services: | Forum | Review | PDF | Favorites | |
