Black Hole Baryogenesis
  We find that the Hawking radiation of black holes can create the baryon number in the Higgs phase vacuum of the extended standard model with 2-Higgs doublets. We propose new scenarios of baryogenesis based on the black holes, and one of our scenarios can explain the origin of baryon number in our universe, if most of the matter existed as primordial black holes.
