Supersymmetric Dark Matter Sectors

TL;DR

This paper explores a supersymmetric dark matter sector where the dark matter candidate remains stable despite R-parity breaking in the visible sector, analyzing its relic density and detection prospects.

Contribution

It introduces a scenario with a stable dark matter candidate in a supersymmetric sector independent of R-parity conservation in the visible sector.

Findings

Dark matter candidate can be stable even with R-parity violation.

Relic density constraints are compatible with the scenario.

Predictions for detection experiments are discussed.

Abstract

We investigate the properties of a dark matter sector where supersymmetry is a good symmetry. In this context we find that the stability of the dark matter candidate is possible even when R-parity is broken in the visible sector. In order to illustrate the idea we investigate a simple scenario where the dark matter candidate is the lightest scalar field in the dark sector which annihilates mainly into two sfermions when these channels are available. We study the relic density constraints and the predictions for the dark matter detection experiments.
