Holographic realization of gauge mediated supersymmetry breaking
The general gauge mediation scenario provides a framework in which properties
of a visible sector with soft supersymmetry breaking are computed from current
correlation functions in the supersymmetry breaking hidden sector. In this
paper we will use holography to model strongly coupled hidden sectors by weakly
curved geometries and describe how the current correlators relevant for general
gauge mediation are computed by holographic methods. We illustrate the general
setup by a toy example which captures most of the relevant features.Comment: 11 pages, v2: comments and refs added, JHEP versio
A consistent truncation of IIB supergravity on manifolds admitting a Sasaki-Einstein structure
Holography for Schrodinger backgrounds
We discuss holography for Schrodinger solutions of both topologically massivegravity in three dimensions and massive vector theories in (d+1) dimensions. Inboth cases the dual field theory can be viewed as a d-dimensional conformalfield theory (two dimensional in the case of TMG) deformed by certain operatorsthat respect the Schrodinger symmetry. These operators are irrelevant from theviewpoint of the relativistic conformal group but they are exactly marginalwith respect to the non-relativistic conformal group. The spectrum of linearfluctuations around the background solutions corresponds to operators that arelabeled by their scaling dimension and the lightcone momentum k_v. We set upthe holographic dictionary and compute 2-point functions of these operatorsboth holographically and in field theory using conformal perturbation theoryand find agreement. The counterterms needed for holographic renormalization arenon-local in the v lightcone direction.<br/
