Warped General Gauge Mediation

TL;DR

This paper develops a formalism for gauge mediation in five-dimensional warped space, enabling calculation of supersymmetry breaking effects and particle masses using current correlators in a slice of AdS.

Contribution

It introduces a novel formalism for general gauge mediation in warped five-dimensional theories, connecting hidden sector dynamics to observable particle masses.

Findings

Current correlators encode SUSY breaking effects in warped space.

Gaugino and sfermion masses are derived from this formalism.

The propagation of SUSY breaking depends on the relation between the warp factor and hidden sector scale.

Abstract

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.
