Charged $B$ Mesogenesis

Abstract

We leverage the CP violation in charged $B$ meson decays to generate the observed baryon asymmetry and dark matter at $\mathcal{O}(10\text{ MeV})$ temperatures. We realize this in two scenarios: $B_c^{+}$ Mesogenesis and $B^{+}$ Mesogenesis. In the first, CP violating $B_c^{\pm }$ decays to $B^{\pm }$ mesons are followed by decays to dark and Standard Model baryons. In the second, CP violating $B^{\pm }$ decays to lighter charged mesons are accompanied by the latter's decays to dark and Standard Model leptons, which then scatter into the baryon asymmetry. $B_c^{+}$ Mesogenesis is actively being probed at Belle and LHCb, while $B^{+}$ Mesogenesis can be tested at colliders and sterile neutrino searches.
