The Quantum Superstring as a WZNW Model with N=2 Superconformal Symmetry
نویسندگان
چکیده
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 anticommuting BRST charges, QS = QW + ∮ γbzz + ∮

N = 4 Superconformal Symmetry for the Covariant Quantum Superstring
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 ant...
متن کاملHybrid Superstrings on Singular Calabi-Yau Fourfolds
Two-dimensional hybrid superstring on singular Calabi-Yau manifolds is studied by the field redefinition of the NSR formalism. The compactification on singular Calabi-Yau fourfold is described by N = 2 super-Liouville theory and N = 2 Landau-Ginzburg models. We examine the world-sheet topological N = 4 superconformal algebra, which is useful to identify physical states of the theory. It is show...
متن کاملOff-Shell Supersymmetry versus Hermiticity in Superstrings.
Superstring theory is the only known renormalizable quantum theory of gravity, and spacetime supersymmetry plays a crucial role in removing the divergences. Spacetime supersymmetry also plays a crucial role in the recent conjectures [1] of strong-weak duality in superstring theory. However, spacetime supersymmetry is only an on-shell symmetry in the conventional N 1 RamondNeveu-Schwarz (RNS) ...
متن کاملSupersymmetric string vacua on AdS3 ×N
String backgrounds of the form AdS 3 × N that give rise to two dimensional spacetime superconformal symmetry are constructed. 1. Introduction In this letter we study the conditions on curved string backgrounds of the form AdS 3 × N that give rise to spacetime superconformal symmetry. We use the NSR formulation; for simplicity we describe the left moving sector only – it can be combined with the...
متن کاملOn gauge/string correspondence and mirror symmetry
We consider a mirror dual of the Berkovits-Vafa A-model for the BPS superstring on AdS5 × S 5 in the form of a deformed superconifold. Via geometric transition, the theory has a dual description as the hermitian gaussian one-matrix model. We show that the A-model amplitudes of AdS2 × S 4 branes, breaking the superconformal symmetry as U(2, 2|4) → OSp(4∗|4), are evaluated in terms of observables...
