Intriguing hints of possible observation of charmless baryonic modes of B decays have prompted us to make theoretical estimates of two and three body decay modes involving baryons in the final state. Bounds on the Kobayashi-Maskawa parameter Vub can then be obtained.

We study the charmful three-body baryonic B decays with D(*) or J/Ψ in the final state. We explain the measured rates of [Formula: see text], [Formula: see text], and [Formula: see text]. In particular, the branching fraction of [Formula: see text] predicted to be of order 2.3 × 10-6 is in accordance with the Belle measurement, [Formula: see text].

Mass Enhancement

We discuss the low-mass enhancement effect in the baryon–antibaryon invariant mass in three-body baryonic B decays using final state interactions in the framework of Regge theory. We show that the rescattering between baryonic pair can reproduce the observed mass spectrum.

Three Body

The status of exclusive two-body and three-body baryonic B decays is reviewed. The threshold enhancement effect in the dibaryon invariant mass and the angular distributions in the dibaryon rest frame are stressed and explained. Weak radiative baryonic B decays mediated by the electromagnetic penguin process b→sγ are discussed. Puzzles with the correlation observed in [Formula: see text] decay and the unexpectedly large rate observed for [Formula: see text] are examined. The former may indicate that the [Formula: see text] system is produced through some intermediate states, while the latter implies the failure of naive factorization for [Formula: see text] modes and may hint at the importance of final-state rescattering effects.

Three Body

In this paper, we investigate the three-body decays of [Formula: see text] meson to [Formula: see text] and [Formula: see text] final state mesons, using a simple model based on the framework of the factorization approach. As we know, there are tree and emission-annihilation diagrams for these decay modes in the factorization approach. We calculate the total [Formula: see text] and [Formula: see text] branching ratios, including the nonresonant and resonances contributions, and in view of the [Formula: see text] mixing, by applying the Dalitz plot analysis and obtain [Formula: see text] and [Formula: see text], while the experimental values are [Formula: see text] and [Formula: see text], respectively. The branching ratios obtained in our model are partly compatible with the experimental results.
