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].

The possibility for the existence of the exotic [Formula: see text] states is explored with the objective of calculating the [Formula: see text] momentum distribution inside such nuclei. Even though the latter is an essential ingredient for the analysis of the experimental data on the [Formula: see text], [Formula: see text] and [Formula: see text] reactions aimed at finding an [Formula: see text]-mesic 3He, the data analysis is usually performed by approximating the [Formula: see text] momentum distribution by that of a nucleon. Here, we present calculations performed by solving the three-body Faddeev equations to obtain the momentum distribution of the [Formula: see text] inside possible ([Formula: see text])[Formula: see text], ([Formula: see text])[Formula: see text] and ([Formula: see text])[Formula: see text]-[Formula: see text] states. The [Formula: see text] momentum distributions are found to be much narrower than those of the nucleons and influence the data selection criteria.

With simple cluster wave functions describing the colliding nuclei, the resonating-group method allows treating collisions realistically with full account of antisymmetrization and of good quantum numbers. The introduction of generator coordinates leads to a striking simplification by allowing the systematic use of Slater determinants. Reactions involving bound and scattering states simultaneously, such as radiative-capture reactions in nuclear astrophysics, are a particularly rich field of applications. In recent years, the microscopic cluster model has evolved to the study of three-body scattering which appears as a final state in a number of processes. The challenge is now to extend microscopic descriptions of collisions to ab initio calculations with realistic forces.

We study the contributions of theB→ψ(3770)K[ψ(3770)→DD̅],B→K*(1410)π[K*(1410)→Kπ], andB→X(3872)K[X(3872)→J/ψγ,ψ(2S)γ,DD-π,J/ψω,J/ψππ, andDD-*π]quasi-two-body decays. There are no existing previous measurements of the three-body branching fractions for three final states of theX(3872)→J/ψγ,ψ(2S)γ, andDD̅π, but several quasi-two-body modes that can decay to this final state have been seen.

We describe the ππS-wave in D+→ π+π−π+ decays using a unitary model for the ππ Final State Interactions (FSI). The three body decay is treated as a quasi two-body process where, at the weak vertex, the D meson decays into a resonance and a pion. The weak part of the decay amplitude is evaluated using the effective weak Hamiltonian within the factorization approximation.
