TL;DR
This paper explores a gravity dual model where supersymmetry breaking in a warped throat geometry is transmitted to the Standard Model through gaugino interactions, highlighting the role of messenger meson splittings.
Contribution
It introduces a holographic framework for gauge mediation of SUSY breaking via warped throat geometries and KK-modes, providing a new perspective on SUSY transmission mechanisms.
Findings
SUSY breaking effects originate from messenger meson splittings.
Gaugino-mediated SUSY breaking is modeled holographically.
The model offers a gravity dual of semi-direct gauge mediation.
Abstract
We discuss gravitational backgrounds where supersymmetry is broken at the end of a warped throat, and the SUSY-breaking is transmitted to the Standard Model via gauginos which live in (part of) the bulk of the throat geometry. We find that the leading effect arises from splittings of certain "messenger mesons," which are adjoint KK-modes of the D-branes supporting the Standard Model gauge group. This picture is a gravity dual of a strongly coupled field theory where SUSY is broken in a hidden sector and transmitted to the Standard Model via a relative of semi-direct gauge mediation.
