Description

CP violation has been observed in neutral meson oscillations, which may explain the matter-antimatter asymmetry of the Universe. We found that a supersymmetric theory with an unbroken U(1)R symmetry and Dirac gauginos can accommodate baryogenesis and asymmetric sneutrino dark matter production via B meson oscillations. This model can be tested via semileptonic asymmetries of B mesons, Flavor violation, exotic B decays, and decay of long-lived particles.
