“…One of the challenges in the study of three body heavy meson decays is the evaluation of matrix elements for heavy meson transition into two hadrons. There are several theoretical approaches to this subject [1][2][3][4][5][6][7]. In [8], a formalism based on the collinear factorization theorem in perturbative QCD (PQCD) for B → P V V was proposed.…”

In this research, we study three body non-leptonic decay B0 → J/ψπ+π− by introducing a two-meson distribution amplitude for the π+π− pair, such that the analysis is simplified into the one for two body decay. By applying the final state interaction, the branching ratio of resonance decay is calculated by generalized factorization and improved quantum chromodynamics factorization (QCDF). Our results are (2.96 ± 0.06) × 10−5 and (4.30 ± 0.02) × 10−5 in these approximations, respectively. In QCDF at an energy scale μ = 2mb, the obtained branching ratio is in agreement with available experimental data: (4.6 ± 0.9) × 10−5.

In this paper, the non-leptonic three-body decays [Formula: see text], [Formula: see text], [Formula: see text] are studied by introducing two-meson distribution amplitude for the [Formula: see text], [Formula: see text] and [Formula: see text] pairs in naive and QCD factorization (QCDF) approaches, such that the analysis is simplified into quasi-two body decays. By considering that the vector meson is being ejected in factorization, the resonant and non-resonant contributions are analyzed by using intermediate mesons in Breit–Wigner resonance formalism and the heavy meson chiral perturbation theory (HMChPT), respectively. The calculated values of the resonant and non-resonant branching ratio of [Formula: see text], [Formula: see text] and [Formula: see text] decay modes are compared with the experimental data. For [Formula: see text] and [Formula: see text], the non-resonant contributions are about 70–80% of experimental data, for which the total results by considering resonant contributions are in good agreement with the experiment.
