Abstract

We report recent observations of baryonic B decays with charmless and charmed baryons in the final state. We show the angular distributions of the di-baryon low-mass enhancements in the charmless three-body baryonic B decays andthe branching fractions of B decays with two charmed baryons or charmonium in the final states. We also report the observation of the decay $\eta_c \to \Lambda \bar{\Lambda}$ at Belle.
