Review of asymmetric dark matter

TL;DR

This review explores asymmetric dark matter models, which link dark matter abundance to matter-antimatter asymmetry, discussing their theoretical construction, cosmological implications, experimental constraints, and detection prospects.

Contribution

It provides a comprehensive overview of the construction, implications, and experimental prospects of asymmetric dark matter models, highlighting recent developments.

Findings

Asymmetric dark matter models relate dark matter abundance to matter-antimatter asymmetry.

Cosmological and astrophysical bounds constrain these models.

Potential detection methods include direct detection and collider signatures.

Abstract

Asymmetric dark matter models are based on the hypothesis that the present-day abundance of dark matter has the same origin as the abundance of ordinary or visible matter: an asymmetry in the number densities of particles and antiparticles. They are largely motivated by the observed similarity in the mass densities of dark and visible matter, with the former observed to be about five times the latter. This review discusses the construction of asymmetric dark matter models, summarizes cosmological and astrophysical implications and bounds, and touches on direct detection prospects and collider signatures.
