The $B$-Mesogenesis framework anticipates decays of $B$ mesons into a dark antibaryon $\Psi$ and various Standard Model baryons. Here, we focus on the exclusive decay process $B\to p \Psi$ observed as a proton and missing energy in the…
We introduce $\text{Dark}_{CP}$ Mesogenesis in which Standard Model mesons, either $B_{s,d}^0$, $B^\pm$ or $B_c^\pm$, undergo out-of-equilibrium dark CP violating decays to Standard Model and dark sector baryons. With order one CP violation…
