Dark Supersymmetry

TL;DR

The paper introduces a Dark Supersymmetry model linking a supersymmetric dark sector to the Standard Model via the Higgs portal, explaining dark matter and electroweak symmetry breaking while remaining consistent with current experimental bounds.

Contribution

It presents a novel Dark Supersymmetry framework where a supersymmetric dark sector influences the Standard Model through the Higgs portal, providing a natural explanation for dark matter and electroweak symmetry breaking.

Findings

Dark matter abundance can be explained with natural parameters.

The model avoids current direct detection experimental bounds.

Future experiments could test the dark sector mass scale.

Abstract

We propose a model of Dark Supersymmetry, where a supersymmetric dark sector is coupled to the classically scale invariant non-supersymmetric Standard Model through the Higgs portal. The dark sector contains a mass scale that is protected against radiative corrections by supersymmetry, and the portal coupling mediates this scale to the Standard Model, resulting in a vacuum expectation value for the Higgs field and the usual electroweak symmetry breaking mechanism. The supersymmetric dark sector contains dark matter candidates, and we show that the observed dark matter abundance is generated for a natural choice of parameters, while avoiding the current experimental bounds on direct detection. Future experiments can probe this scenario if the dark sector mass scale is not too high.
