Constraints on the mass of the dark antibaryon using $B_d\rightarrow Λψ_{DS}$ channel in light cone QCD

According to the $B$-mesogenesis framework, the baryon asymmetry of the Universe and dark matter can be simultaneously generated through CP-violating $B$-meson oscillations. In this mechanism, $B$-mesons decay into a Standard Model baryon and a dark-sector antibaryon, denoted by $ψ_{DS}$. Within thi
