We study the doubly charmed baryonic B decays $B\to \Xi_{c} \Lambda_{c}$ and $B\to \Lambda^{+}_{c} \Lambda^{-}_{c} K$, recently observed by BELLE. We find that the unexpected large branching ratios (BRs) could be ascribed to the final state…

We report first measurements of the doubly charmed baryonic B decays B->Lambda_c+Lambda_c-K. The B+->Lambda_c+Lambda_c-K+ decay is observed with a branching fraction of (6.5+1.0-0.9+-1.1+-3.4)x10^{-4} and a statistical significance of…

We give the first estimate of charmless scalar meson emitting weak hadronic decays of 0 $\Lembda_{b}^{0}$, $\Xi_{b}^{0}$ and $\Xi_{b}^{-}$ bottom baryons employing the pole model and consequently predict their branching ratios.
Three-body decay of charmed baryons $\Lambda^*_c(2595)$ and $\Lambda^*_c(2625)$ into $\Lambda_c \pi \pi$ are studied with effective Lagrangians in which the coupling constants are extracted from the non-relativistic quark model. We take…
