This article investigates the decays of B mesons into baryons and dark antibaryons, specifically the exclusive decay mode B+ → p &UPsi;. The authors propose a method to calculate the amplitude of this decay and estimate the decay width as a function of the mass and effective coupling of the dark antibaryon.
The recently developed B-Mesogenesis scenario predicts decays of B mesons into a baryon and hypothetical dark antibaryon & UPsi;. We suggest a method to calculate the amplitude of the simplest exclusive decay mode B+ & RARR; p & UPsi;. Considering two models of B-Mesogenesis, we obtain the B & RARR; p hadronic matrix elements by applying QCD light-cone sum rules with the proton light-cone distribution amplitudes. We estimate the B+ & RARR; p & UPsi; decay width as a function of the mass and effective coupling of the dark antibaryon. (c) 2022 The Authors. Published by Elsevier B.V.
