Charmful Three-body Baryonic B 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 $B^{-}\to \Lambda \bar{p}J/\Psi$ and predict the branching fractions of ${\bar{B}}^0\to \Lambda \bar{p}{D}^{\ast +}$, ${\bar{B}}^0\to {\Sigma }^0\bar{p}{D}^{\ast +}$, $B^{-}\to \Lambda \bar{p}{D}^0$, and $B^{-}\to \Lambda \bar{p}{D}^{\ast 0}$ to be of order $(1.2,1.1,1.1,3.9)\times 10^{-5}$, respectively. They are readily accessible to the $B$ factories.
