Supersymmetry Breaking through Transparent Extra Dimensions

TL;DR

This paper introduces a novel extra-dimensional framework for supersymmetry breaking that naturally produces positive scalar masses and addresses flavor issues, with implications for particle spectra and collider experiments.

Contribution

It presents a new mechanism where supersymmetry breaking occurs on a separate brane, leading to distinctive mass generation and solving flavor problems in supersymmetric models.

Findings

Predicts positive scalar masses consistent with phenomenology.

Provides a mechanism for supersymmetry breaking mediation via extra dimensions.

Discusses potential collider signatures and spectrum implications.

Abstract

We propose a new framework for mediating supersymmetry breaking through an extra dimension. It predicts positive scalar masses and solves the supersymmetric flavor problem. Supersymmetry breaks on a ``source'' brane that is spatially separated from a parallel brane on which the standard model matter fields and their superpartners live. The gauge and gaugino fields propagate in the bulk, the latter receiving a supersymmetry breaking mass from direct couplings to the source brane. Scalar masses are suppressed at the high scale but are generated via the renormalization group. We briefly discuss the spectrum and collider signals for a range of compactification scales.
