“…The "large N" limit of Seiberg duality will clearly yield a version of the metastable supersymmetry breaking mechanism of Intriligator, Seiberg and Shih [3], but in an RS1 configuration similar to those discussed in Refs. [36,37]. (A string configuration that corresponds to this case was presented in Ref.…”

“…Here we begin with the "simplified gauge mediation" scenario of Murayama and Nomura [35]. We show that taking the large N limit of this theory as described above yields a gaugino mediation model in AdS, with metastable supersymmetry breaking on the IR-brane, matter and messenger fields on the UV brane and gauge fields in the bulk, a scenario that has been considered in a number of phenomenological applications [36,37]. As in conventional gaugino mediation, the scalar mass squareds are generated by (5D) one loop diagrams that are relatively suppressed due to the bulk separation of matter fields and supersymmetry breaking.…”

A slice of AdS 5 is used to provide a 5D gravitational description of 4D stronglycoupled Seiberg dual gauge theories. An (electric) SU(N ) gauge theory in the conformal window at large N is described by the 5D bulk, while its weakly coupled (magnetic) dual is confined to the IR brane. This framework can be used to construct an N = 1 MSSM on the IR brane, reminiscent of the original Randall-Sundrum model. In addition, we use our framework to study strongly-coupled scenarios of supersymmetry breaking mediated by gauge forces. This leads to a unified scenario that connects the extra-ordinary gauge mediation limit to the gaugino mediation limit in warped space.

“…There are several benefits of using a holographic approach in this context, some of which were suggested in Refs. [17,18]. As already mentioned, the UV theory can maximally break R-symmetry, but the theory on the IR brane maintains an approximate R-symmetry.…”

“…Before turning to the specifics of our model, we should briefly comment on the relation of our work to Ref. [17] which also considered metastability in a holographic set-up. That work discussed tunnelling in a theory which was equivalent to the magnetic theory of ISS, but with the superpotential terms split between the IR and UV branes (e.g.…”

We show how supersymmetric QCD in a slice of AdS can naturally acquire metastable vacua. The formulation closely follows that of Intriligator, Seiberg and Shih (ISS), with an "electric" sector on the UV brane and a "magnetic" sector on the IR brane. However the 't Hooft anomaly matching that constrains the Seiberg duality central to ISS is replaced by anomaly inflow and cancellation, and the source of strong coupling is the CFT to which the theory couples rather than the gauge groups. The theory contains an anomaly free R-symmetry that, when broken by UV effects, leads to an O'Raifeartaigh model on the IR brane. In contrast to ISS, the R-symmetry breaking in the UV can be maximal, and yet the R-symmetry breaking in the IR theory remains under strict control: there is no need for retrofitting of small parameters.Comment: 20 pages, 2 figure

We develop the formalism of "General gauge mediation" for five-dimensional theories in a slice of AdS space. A set of current correlators encodes the effect of a supersymmetry breaking hidden sector localised on the IR brane. These current correlators provide a tree-level gaugino mass and loop-level sfermion masses on the UV brane. We also use this formalism to calculate the Casimir energy and masses for bulk hyperscalars.To illustrate this general construction we consider a perturbative hidden sector of generalised messengers coupled to a spurion. For models with large warping, we find that when the AdS warp factor k is less than the characteristc mass scale M of the hidden sector, the whole Kaluza-Klein tower of vector superfields propagate supersymmetry breaking effects to the UV brane. When M is less than k, the zero modes dominate. † m.mcgarrie@qmul.ac.uk ‡ dthompson@tena4.vub.ac.be
