Charmful baryonic B\to {\bf B\bar B'}M_c decays

Abstract

We study the charmful three-body baryonic B decays with $D^{(\ast )}$ or $J/\Psi$ in the final state. We explain the measured rates of ${\bar{B}}^0\to n\bar{p}{D}^{\ast +}$, ${\bar{B}}^0\to p\bar{p}{D}^{(\ast )0}$, 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, $(1.05_{-0.44}^{+0.57}\pm 0.14)\times 10^{-5}<2.6\times 10^{-5}$.
