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.

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.

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.
