Study of $\bar{B}\to \Lambda \bar{p}\rho (\varphi )$ and $\bar{B}\to \Lambda \bar{\Lambda }{\bar{K}}^{\ast }$

Abstract

We examine the three-body baryonic $\bar{B}\to \mathbf{B}{\bar{\mathbf{B}}}^{\prime }V$ decays with $V$ vector mesons in the standard model. We can simultaneously explain the recent experimental data on the decays of $B^{-}\to \Lambda \bar{p}{\rho }^0$ and $\bar{B}\to \Lambda \bar{\Lambda }{\bar{K}}^{\ast }$ based on the QCD counting rules and SU(3) flavor symmetry. We also predict that the decay branching ratios of ${\bar{B}}^0\to \Lambda \bar{p}{\rho }^{+}$ and $B^{-}\to \Lambda \bar{p}\varphi$ are 3.0 and $1.5\times 10^{-6}$, respectively, which are promising to be observed by BELLE and BABAR at the $B$ factories.
