Description

We propose a model of baryogenesis achieved by the annihilation of non-thermally produced WIMPs from Primordial Black Hole (PBH). Dark Matter (DM) particles can be produced by PBH evaporation and consequently re-annihilate into lighter particles even after thermal freeze-out. The re-annihilation of DM provides the observed baryon asymmetry and the correct relic abundance of DM depending on the PBH evaporation temperature.
