Baryogenesis and Dark Matter from B Mesons

In the B-Mesogenesis paradigm, the CP violating oscillations and subsequent decays of B mesons in the early Universe simultaneously explain the origin of the baryonic and the dark matter of the Universe. Leveraging the predictions of the early Universe dynamics, this mechanism for low-scale baryo- and dark matter-genesis could be discovered at B-factories and the LHC. A combination of CP violating observables in the neutral B meson system, exotic decays of B mesons into a visible baryon and missing energy, and direct searches for a TeV-scale colored scalar at the LHC, together with a number of indirect astrophysical probes, could allow to fully test B-Mesogenesis in the near future.
