Description | Joint Theory Seminar Speaker: Anson Hook (IAS) Title: Asymmetric Hawking Radiation : Baryogenesis from Hawking Radiation Host: Yuhsin Tsai Room: 432 Abstract: We show that in the presence of a chemical potential, black hole evaporation generates baryon number. If the inflaton or Ricci scalar is derivatively coupled to the B-L current, the expansion of the universe acts as a chemical potential and splits the energy levels of particles and their anti-particles. The asymmetric Hawking radiation of primordial black holes can thus be used to generate a B-L asymmetry. If dark matter is produced by the same mechanism, the coincidence between the mass density of visible and dark matter can be naturally explained. |
