New Models of Baryogenesis

Description
I will describe a new mechanism for creating the matter-antimatter asymmetry of the Universe at low temperatures, i.e. below the QCD confinement temperature, involving the CP-violating oscillation of fermions made of strongly interacting particles. I will also make connections to neutron-antineutron oscillations, clearing up issues that exist in the literature. Novel experimental tests will be discussed.
