Asymmetric Dark Matter from Hidden Sector Baryogenesis

TL;DR

This paper proposes a supersymmetric model where asymmetric dark matter and baryon asymmetry are generated simultaneously in a hidden sector baryogenesis process, with potential collider and detection signatures.

Contribution

It introduces a novel supersymmetric framework linking dark matter production to hidden sector baryogenesis, matching dark matter and baryon densities.

Findings

Dark matter candidate has similar number density to baryons

Dark matter mass is comparable to b, c quarks and tau leptons

Model predicts specific collider and direct detection signatures

Abstract

We consider the production of asymmetric dark matter during hidden sector baryogenesis. We consider a particular supersymmetric model where the dark matter candidate has a number density approximately equal to the baryon number density, with a mass of the same scale as the $b$, $c$ and $\tau$. Both baryon asymmetry and dark matter are created at the same time in this model. We describe collider and direct detection signatures of this model.
