We investigate theB0→J/ψηK0andB+→J/ψηK+decay by using the Dalitz plot analysis. As we know there are tree, penguin, emission, and emission-annihilation diagrams for these decay modes in the factorization approach. The transition matrix element is factorized into aB→ηKform factor multiplied byJ/ψdecay constant and also aB→Kform factor multiplied byJ/ψηdecay constant. According to QCD factorization approach and using the Dalitz plot analysis, we calculate the branching ratios of theB0→J/ψηK0andB+→J/ψηK+three-body decay in view of theη-η'mixing and obtain the value of the(9.22-1.47+2.67)×10-5, while the experimental results of them are(8±4)×10-5and(10.8±3.3)×10-5, respectively. In this research we also analyze theB(Bs)→ηcπK*decay which is similar to the previous decay, but there is no experimental data for the last decay. Since for calculations of theB(Bs)→ηcπK*decay we use assumptions of theB→J/ψηKdecay, we hope that if this decay will be measured by the LHCb in the future, the experimental results will be in agreement with our calculations.

We investigate the [Formula: see text] decay using Dalitz plot analysis. There are two tree diagrams for this decay mode in the factorization approach: the transition matrix element is factorized into a B0 → π+π− form factor multiplied by [Formula: see text] decay constant; and a [Formula: see text] form factor multiplied by a π+ decay constant. In this research we evaluate the matrix elements of the vector and axial vector currents between the B0 and [Formula: see text] meson states by using the B*+ pole. The contributions of intermediate resonances, such as f0(980), f0(1370), f0(1500) and ρ(770), ρ(1450), ρ(1700), have been taken into account. According to the QCD factorization approach and using Dalitz plot analysis, we calculate the branching ratio of [Formula: see text] decay and obtain 3.81 ± 1.31 × 10−4 and 7.49 ± 2.71 × 10−4 at the μ = mb and 2mb scales, respectively, whereas the experimental result is (6.20 ± 2.20) × 10−4.

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.

Computation Analysis

The aim of this work is to provide a phenomenological analysis of the contribution of [Formula: see text] meson to [Formula: see text], [Formula: see text] and [Formula: see text] quasi-three-body decays. Such that the analysis of mentioned four-body decays is summarized into three-body decay and several channels are observed. Based on the factorization approach, hadronic three-body decays receive both resonant and nonresonant contributions. We compute both contributions of three-body decays. As, there are tree, penguin, emission, and emission annihilation diagrams for these decay modes. Our theoretical model for [Formula: see text] decay is based on the QCD factorization to quasi-two body followed by [Formula: see text]-wave. This model for this decay following experimental information which demonstrated two pion interaction in the [Formula: see text]-wave is introduced by the scalar resonance. The theoretical values are [Formula: see text], [Formula: see text] and [Formula: see text], while the experimental results of them are [Formula: see text], [Formula: see text] and [Formula: see text], respectively. Comparing computation analysis values with experimental values show that our results are in agreement with them.

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.

We also perform Dalitz plot analyses of the J/Ψ decays to π+π−π0, K+K−π0 and K0sK±π∓ produced in the initial state radiation process.

Abstract CP violation in charm decay was observed in the decays D0→ P±P∓ of a D0 meson to two pseudoscalars. When interpreted within the SM, the results imply that the ratio of the relevant rescattering amplitudes has a magnitude and phase that are both of O(1). We discuss ways to probe similar ratios in D0→ V±P∓ decays, where V is a vector that decays to two pseudoscalars, from the Dalitz-plot analysis of time-integrated three-body decays. Compared to two-body decays, three-body decays have the advantage that the complete system can be solved without the need for time-dependent CP violation measurements or use of correlated $$ {D}^0-{\overline{D}}^0 $$ D 0 − D ¯ 0 production. We discuss the decays D0→ π+π−π0 and D0→ K+K−π0 as examples by considering a toy model of only two overlapping charged resonances, treating the underlying pseudo two-body decays in full generality.
