The $B$-Mesogenesis framework anticipates decays of $B$ mesons into a darkantibaryon $\Psi$ and various Standard Model baryons. Here, we focus on theexclusive decay process $B\to p \Psi$ observed as a proton and missing energyin the final state and determine the decay width by employing the QCDlight-cone sum rule framework. We include all contributions up to twist six tothe nucleon distribution amplitudes in order to parameterize thenon-perturbative effects in the operator product expansion. We obtain the decaywidth and branching fraction with respect to the mass $m_{\Psi}$ of the darkantibaryon $\Psi$, normalized to the model-dependent effective four-fermioncoupling.
