Contribution

It provides a theoretical analysis of baryonic B decays with charm mesons and J/, matching experimental results and offering predictions for unmeasured decay modes.

Findings

Measured decay rates are explained by the model.

Predicted branching fraction for  o  D^0 matches Belle data.

Predictions are consistent with existing experimental bounds.

Abstract

We study the charmful three-body baryonic B decays with $D^{(*)}$ or $J/\Psi$ in the final state. We explain the measured rates of $\bar B^0\to n\bar p D^{*+}$, $\bar B^0\to p\bar p D^{(*)0}$, and $B^-\to \Lambda \bar p J/\Psi$. In particular, the branching fraction of $\bar B^0\to\Lambda\bar \Lambda D^0$ predicted to be of order $2.3\times 10^{-6}$ is in accordance with the Belle measurement, $(1.05^{+0.57}_{-0.44}\pm 0.14)\times 10^{-5}<2.6\times 10^{-5}$.
