Melanopogenesis: dark matter of (almost) any mass and baryonic matter from the evaporation of primordial black holes weighing a ton (or less)
- Univ. of California, Santa Cruz, CA (United States)
The evaporation of primordial black holes with a mass in the 1 gram≲ MPBH≲1000 kg range can lead to the production of dark matter particles of almost any mass in the range 0.1 MeV≲ mDM≲ 1018 GeV with the right relic density at very early times, τ≲ 10-10 s. We calculate, as a function of the primordial black holes mass and initial abundance, the combination of dark matter particle masses and number of effective dark degrees of freedom leading to the right abundance of dark matter today, whether or not evaporation stops around the Planck scale. In addition, since black hole evaporation can also lead to the production of a baryon asymmetry, we calculate where dark matter production and baryogenesis can concurrently happen, under a variety of assumptions: baryogenesis via grand unification boson decay, via leptogenesis, or via asymmetric co-genesis of dark matter and ordinary matter. Finally, we comment on possible ways to test this scenario.
