N = 4 Superconformal Symmetry for the Covariant Quantum Superstring
نویسنده
چکیده
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 QS and a charge QV proposed by Dijkgraaf, Verlinde and Verlinde for topological models. Using our recent work on ”gauging cosets”, we then construct a further charge QC which anticommutes with QS+QV and which is intended for the definition of the physical spectrum.

The Quantum Superstring as a WZNW Model with N=2 Superconformal Symmetry
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 (bzz, c , βzz, γ ) for topological gravity. The currents of this combined system form an N = 2 superconformal algebra. The model has vanishing central charge and contains two ant...

We show that the Lorentz covariant formulation of N = 2 string in a curved space reveals the hyper–Kähler structure. Apart from the metric, the superconformal currents couple to a background two–form. By superconformal symmetry the latter is constrained to be holomorphic and covariantly constant and allows one to construct three complex structures in an explicit form. PACS: 04.60.Ds; 11.30.Pb

متن کاملGreen-Schwarz Superstrings on AdS3 and the Boundary N = 4 Superconformal Algebra
We study the hybrid formulation of Green-Schwarz superstrings on AdS3 with NS flux and the boundary N = 4 superconformal algebra. We show the equivalence between the NSR and GS superstrings by a field redefinition. The boundary N = 4 superconformal algebra is realized by the free fields of the affine Lie superalgebra A(1|1)(1). We also consider the light-cone gauge and obtain the N = 4 superLio...
