TL;DR
This paper proposes a novel dark matter paradigm where an early universe asymmetry is transferred to ordinary matter, fitting within weak scale physics models and involving natural suppression mechanisms like lepton-violating operators.
Contribution
It introduces a new dark matter framework with asymmetry transfer mechanisms compatible with weak scale physics, including natural suppression processes.
Findings
Dark matter candidate mass is around the weak scale.
Asymmetry transfer to ordinary matter is feasible via lepton-violating operators.
The scenario integrates naturally into existing weak scale models.
Abstract
We present a new paradigm for dark matter in which a dark matter asymmetry is established in the early universe that is then transferred to ordinary matter. We show this scenario can fit naturally into weak scale physics models, with a dark matter candidate mass of this order. We present several natural suppression mechanisms, including bleeding dark matter number density into lepton number, which occurs naturally in models with lepton-violating operators transferring the asymmetry.
