The Perturbation Spectrum of Black Holes in N = 8 Supergravity
The near horizon geometry of four-dimensional black holes in the dilute gas regime is AdS3 × S 2, and the global symmetry group is SU(2)×USp(6). This is exploited to calculate their perturbation spectrum using group theoretical methods. The result is interpreted in terms of three extreme M5-branes, orthogonally intersecting over a common string. We also consider N = 8 black holes in five dimens...
متن کاملGlueball Mass Spectrum from Supergravity∗
We review the calculation of the spectrum of glueball masses in non-supersymmetric Yang-Mills theory using the conjectured duality between supergravity and large N gauge theories. The glueball masses are obtained by solving the supergravity wave equations in a black hole geometry. The glueball masses found this way are in unexpected agreement with the available lattice data. We also show how to...
متن کاملN = 8 Supergravity on the Light Cone
We construct the generating functional for the light-cone superfield amplitudes in a chiral momentum superspace. It generates the n-point particle amplitudes which on shell are equivalent to the covariant ones. Based on the action depending on unconstrained light-cone chiral scalar superfield, this functional provides a regular d=4 QFT path integral derivation of the Nair-type amplitude constru...
متن کاملHigher spin N = 8 supergravity
The product of two N = 8 supersingletons yields an infinite tower of massless states of higher spin in four dimensional anti de Sitter space. All the states with spin s ≥ 1 correspond to generators of Vasiliev’s super higher spin algebra shsE(8|4) which contains the D = 4, N = 8 anti de Sitter superalgebra OSp(8|4). Gauging the higher spin algebra and introducing a matter multiplet in a quasi-a...
متن کاملMass Spectrum of D = 11 Supergravity on AdS 2 × S
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...
