Xogenesis

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 occur naturally in models with lepton-violating operators transferring the asymmetry that reduce the number density and allow for dark matter much heavier than baryon masses.
