Pangenesis: a common origin for visible and dark matter

TL;DR

This paper proposes 'pangenesis', a mechanism using the Affleck-Dine process in a baryon-symmetric universe, to explain the similar mass densities of visible and dark matter as evidence of a common origin.

Contribution

It introduces 'pangenesis' as a novel theoretical framework linking the origins of visible and dark matter through a baryon-symmetric universe.

Findings

Pangenesis provides a unified origin for visible and dark matter.

The Affleck-Dine mechanism is adapted for baryon symmetry in this context.

The model explains the observed mass density similarities.

Abstract

The similar mass densities observed for visible and dark matter in the present-day universe suggest a common origin for both. A scheme called "pangenesis" for realising this using the Affleck-Dine mechanism in a baryon-symmetric universe is presented in this talk.
