Superstring Theory on AdS 3 × G / H and Boundary N = 3 Superconformal Symmetry
Superstrings propagating on backgrounds of the form AdS3 ×G/H are studied using the coset CFT approach. We focus on seven dimensional cosets which have a semiclassical limit, and which give rise to N = 3 superconformal symmetry in the dual CFT. This is realized for the two cases AdS3 × SU(3)/U(1) and AdS3 × SO(5)/SO(3), for which we present an explicit construction. We also provide sufficient c...
متن کاملHybrid Superstring on AdS3 and Space-Time Superconformal Symmetry
Using the hybrid formalism, superstring on AdS3 ×S1 is studied in a manifest supersymmetric manner. The world-sheet fields in this description including superspace coordinates are obtained through a field redefinition from the corresponding ones in the RNS formalism. The physical states are defined by the BRST cohomology as an N = 4 topological string theory. The physical spectra for some lower...
متن کاملSuperconformal Algebras on the Boundary of AdS3
Motivated by recent progress on the correspondence between string theory on anti-de Sitter space and conformal field theory, we provide an explicit construction of an infinite dimensional class of superconformal algebras on the boundary of AdS3. These space-time algebras are N extended superconformal algebras of the kind obtainable by hamiltonian reduction of affine SL(2|N/2) current superalgeb...
متن کاملN = 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 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...
