Holographic metastability

Abstract

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

Holography for general gauge mediation

“…In particular the AdS/QCD programme [5][6][7][8] has developed "bottom-up" models that apply the ideas and perspectives of gauge/gravity duality to QCD. Inspired by these we wish to explore AdS/✘ ✘ ✘ ✘ SUSY models as initiated in [9][10][11][12][13][14][15][16][17][18][19]. Similar to AdS/QCD, the idea is to construct a setup which attempts to describe a large N c SQCD model with a spontaneous supersymmetry breaking sector.…”

General resonance mediation

“…This demonstrates much of the utility of general gauge mediation [3] and is a concrete model from which to extract the various form factors for both sfermion masses and cross sections. This section overlaps with the hidden local symmetry program of AdS/QCD [66] and shares features with [8,9,13,67], which we will abbreviate to AdS/✘ ✘ ✘ ✘ SUSY. In analogy to hidden local symmetry models [15,66], we apply a type of Wilsonian matching, where we wish to analyse a system which is described by an effective theory…”

“…In other words the assumption is made that vector mesons participate in the mediation. Whilst this is naturally the case in five dimensional models [7][8][9][10][11][12][13][14], and these will be used as examples, it is hoped that these results will have application for theories that are four dimensional and strongly coupled, such as in [15].…”

SU(7) unification of SU(3) C × SU(4) W × U(1) B−L

“…Anomaly matching in the Seiberg duality is equivalent to anomaly inflow of the Chern-Simmons terms of the 5D bulk, which gives opposite contributions on the two boundaries [58]. According to the setup of the conformal supersymmetry breaking scenario, we require the theory to enter a superconformal region when we can neglect the masses of P and P .…”
