Exploring Holographic General Gauge Mediation

TL;DR

This paper investigates holographic models of gauge mediation with strongly coupled hidden sectors, analyzing how boundary conditions affect the soft spectrum and exploring R-symmetry breaking effects.

Contribution

It introduces a holographic dual framework for gauge mediation, showing how boundary conditions influence the soft spectrum and connecting bottom-up models with top-down approaches.

Findings

Boundary conditions determine the presence of vector and fermion poles.

Certain boundary choices cover the full GGM parameter space.

R-symmetry breaking scalars constrain the soft term structure.

Abstract

We study models of gauge mediation with strongly coupled hidden sectors, employing a hard wall background as an holographic dual description. The structure of the soft spectrum depends crucially on the boundary conditions one imposes on bulk fields at the IR wall. Generically, vector and fermion correlators have poles at zero momentum, leading to gauge mediation by massive vector messengers and/or generating Dirac gaugino masses. Instead, non-generic choices of boundary conditions let one cover all of GGM parameter space. Enriching the background with R-symmetry breaking scalars, the SSM soft term structure becomes more constrained and similar to previously studied top-down models, while retaining the more analytic control the present bottom-up approach offers.
