“…In this study, we systematically analyze the contributions from in the decays using the PQCD approach [30][31][32][33], which has previously been adopted to study three-body B meson decays [34][35][36][37][38]. With the help of experimental inputs for time-like pion form factors [39] and two-pion distribution amplitudes [40][41][42], the decays [43], [44], [45], and [46] are analyzed in the quasi-two-body framework. The method used in [43] have been adopted for other quasi-two-body B meson decays in Refs.…”

Within the framework of perturbative QCD factorization, we investigate the nonfactorizable contributions to these factorization-forbidden Quasi-two-body decays $B_{(s)}\rightarrow h\chi_{c0}\rightarrow h\pi^+\pi^-(K^+K^-)$ with $ h=\pi, K $. We compare our predicted branching ratios for the $B_{(s)}\rightarrow K\chi_{c0}\rightarrow K\pi^+\pi^-(K^+K^-)$ decay with available experiment data as well as predictions by other theoretical studies. The branching ratios of these decays are consistent with data and other theoretical predictions. In the Cabibbo-suppressed decays $B_{(s)}\rightarrow h\chi_{c0}\rightarrow h\pi^+\pi^-(K^+K^-)$ with $h=\bar{K}^0,\pi$, however, the values of the branching ratios are the order of $10^{-7}$ and $10^{-8}$. The ratio $R_{\chi_{c0}}$ between the decay $B^+\rightarrow \pi^+\chi_{c0}\rightarrow \pi^+\pi^+\pi^-$ and $B^+\rightarrow K^+\chi_{c0}\rightarrow K^+\pi^+\pi^-$ and the distribution of branching ratios for different decay modes in invariant mass are considered in this work.

The decays $$ B\to {\overline{D}}^{\left(\ast \right)}\omega \pi $$ B → D ¯ ∗ ωπ are very important for the investigation of ρ excitations and the test of factorization hypothesis for B meson decays. The $$ {B}^{+}\to {\overline{D}}^{\left(\ast \right)0}\omega {\pi}^{+} $$ B + → D ¯ ∗ 0 ω π + and B0 → D(*)−ωπ+ have been measured by different collaborations but without any predictions for their observables on theoretical side. In this work, we study the contributions of ρ(770, 1450) → ωπ for the cascade decays $$ {B}^{+}\to {\overline{D}}^{\left(\ast \right)0}{\rho}^{+}\to {\overline{D}}^{\left(\ast \right)0}\omega {\pi}^{+} $$ B + → D ¯ ∗ 0 ρ + → D ¯ ∗ 0 ω π + , B0 → D(*)−ρ+ → D(*)−ωπ+ and $$ {B}_s^0\to {D}_s^{\left(\ast \right)-}{\rho}^{+}\to {D}^{\left(\ast \right)-}\omega {\pi}^{+} $$ B s 0 → D s ∗ − ρ + → D ∗ − ω π + . We introduce ρ(770, 1450) → ωπ subprocesses into the distribution amplitudes for ωπ system via the vector form factor Fωπ(s) and then predict the branching fractions for the first time for concerned quasi-two-body decays with ρ(770, 1450) → ωπ, as well as the corresponding longitudinal polarization fractions ΓL/Γ for the cases with the vector $$ {\overline{D}}^{\ast 0} $$ D ¯ ∗ 0 or $$ {D}_{(s)}^{\ast -} $$ D s ∗ − in their final states. The branching fractions of these quasi-two-body decays are predicted at the order of 10−3, which can be detected at the LHCb and Belle-II experiments. The predictions for the decays B0 → D*−ρ(770)+ → D*−ωπ+ and B0 → D*−ρ(1450)+ → D*−ωπ+ agree well with the measurements from Belle Collaboration. In order to avoid the pollution from annihilation Feynman diagrams, we recommend to take the $$ {B}_s^0\to {D}_s^{\ast -}\rho {\left(770,1450\right)}^{+} $$ B s 0 → D s ∗ − ρ 770 1450 + decays, which have only emission diagrams at quark level, to test the factorization hypothesis for B decays.

The contributions for kaon pair from the intermediate states $\rho(1450)^+$ and $\rho(1700)^+$ in the decays of $B^+ \to \bar{D}^0 K^+ \bar{K}^0$, $B^0 \to D^- K^+ \bar{K}^0$ and $B_s^0 \to D_s^-K^+ \bar{K}^0$ are analyzed within the perturbative QCD factorization approach. The decay amplitudes for all concerned decays in this work are dominated by the factorizable Feynman diagrams with the emission of the kaon pair, and the charged $\rho$ mesons should be of great importance in the $KK$ channel of the related three-body $B$ decays. Besides, these quasi-two-body decays are CKM-favored and the relevant branching ratios are predicted in the order of $10^{-5}$, which are potential to be measured by experiments. It is also shown that the contributions of the subprocesses $\rho(1450, 1700)^+ \to KK$ for the three-body $B$ meson decays are considerable according to the total three-body branching fractions presented by Belle. Therefore, the decays $B^+ \to \bar{D}^0 K^+ \bar{K}^0$, $B^0 \to D^- K^+ \bar{K}^0$ and $B_s^0 \to D_s^-K^+ \bar{K}^0$ can be employed to study the properties of $\rho(1450)$ and $\rho(1700)$ in the LHCb and Belle-II experiments.
