Melanopogenesis: dark matter of (almost) any mass and baryonic matter from the evaporation of primordial black holes weighing a ton (or less)

The evaporation of primordial black holes with a mass in the 1\\ \\ M\ ₏₁₇\1000 kg range can lead to the production of matter particles of almost any mass in the range 0. 1\\ \ MeV\\ ₃₌\ 10^18 GeV with the right relic density at very early, \\ 10^-10 s. We calculate, as a function of the primordial holes mass and initial abundance, the combination of dark matter particle and number of effective dark degrees of freedom leading to the right of dark matter today, whether or not evaporation stops around the scale. In addition, since black hole evaporation can also lead to the of a baryon asymmetry, we calculate where dark matter production and can concurrently happen, under a variety of assumptions: via grand unification boson decay, via leptogenesis, or via co-genesis of dark matter and ordinary matter. Finally, we comment possible ways to test this scenario.
