Supergravity spectrum on AdS 2 × S 2
نویسنده
چکیده
The Kaluza-Klein spectrum of N=2, D=4 supergravity compactified on AdS2×S is found and shown to consist of two infinite towers of SU(1, 1|2) representations. In addition to ‘pure gauge’ modes living on the boundary of AdS which are familiar from higher dimensional cases, in two dimensions there are modes (e.g. massive gravitons) which enjoy no gauge symmetry yet nevertheless have no on-shell degrees of freedom in the bulk. We discuss these two-dimensional subtleties in detail. [email protected]. Address after Sept. 1: New High Energy Theory Center; Rutgers University; 126 Frelinghuysen Road; Piscataway, NJ 08854.

On N=8 Supergravity in AdS5 and N=4 Superconformal Yang-Mills theory
We discuss the spectrum of states of IIB supergravity on AdS 5 ×S 5 in a manifest SU (2, 2/4) invariant setting. The boundary fields are described in terms of N = 4 superconformal Yang-Mills theory and the proposed correspondence between supergravity in AdS 5 and superconformal invariant singleton theory at the boundary is formulated in a N = 4 superfield covariant language.

متن کاملSpectrum of D = 6 , N = 4 b Supergravity on AdS
The complete spectrum of D = 6, N = 4b supergravity with n tensor multiplets compactified on AdS 3 × S 3 is determined. The D = 6 theory obtained from the K 3 compactification of Type IIB string requires that n = 21, but we let n be arbitrary. The superalgebra that underlies the symmetry of the resulting supergravity theory in AdS 3 coupled to matter is SU (1, 1|2) L × SU (1, 1|2) R. The theory...
متن کاملMass Spectrum of D = 11 Supergravity on AdS 2 × S 2 × T 7
We compute the Kaluza-Klein mass spectrum of the D = 11 supergravity compactified on AdS2× S × T 7 and arrange it into representations of the SU(1, 1|2) superconformal algebra. This geometry arises in M theory as the near horizon limit of a D = 4 extremal black-hole constructed by wrapping four groups of M-branes along the T . Via AdS/CFT correspondence, our result gives a prediction for the sp...
