Brian Shuve - Baryogenesis from Dark Matter Freeze-In

Models of freeze in feature a departure from equilibrium over an extended period of the early universe’s history, and they can naturally give rise to the observed matter-antimatter asymmetry. I will present recent developments in freeze-in baryogenesis, including a novel, testable mechanism for the simultaneous production of dark matter and baryogenesis via CP-violating dark matter oscillations. I will highlight the connections between the early universe dynamics and phenomenology, including tests at colliders, and in cosmological and astrophysical observables.
