B-meson decay into a proton and dark antibaryon from QCD light-cone sum rules
The recently developed B-Mesogenesis scenario predicts decays of B mesons into a baryon and hypothetical dark antibaryon Ψ. We suggest a method to calculate the amplitude of the simplest exclusive decay mode B+→pΨ. Considering two models of B-Mesogenesis, we obtain the B→p hadronic matrix elements b...

| description | The recently developed B-Mesogenesis scenario predicts decays of B mesons into a baryon and hypothetical dark antibaryon Ψ. We suggest a method to calculate the amplitude of the simplest exclusive decay mode B+→pΨ. Considering two models of B-Mesogenesis, we obtain the B→p hadronic matrix elements by applying QCD light-cone sum rules with the proton light-cone distribution amplitudes. We estimate the B+→pΨ decay width as a function of the mass and effective coupling of the dark antibaryon. |
