In the two-quark model supposition for the meson a0(1450), which can be viewed as either the first excited state (scenario I) or the lowest lying state (scenario II), the branching ratios and the direct CP-violating asymmetries for decays B → a0(1450)ρ(ω) are studied by employing the perturbative QCD factorization approach. We find the following results: (a) For the decays B− → a00(1450)ρ− and B̄0 → a+0(1450)ρ−, their branching ratios have large difference between two scenarios. Although their branching ratios are larger than other considered decay modes, their direct CP-violating asymmetries in both scenarios are small. (b) For the decays B− → a−0(1450)ρ0 and B̄0 → a−0(1450)ρ+, a00(1450)ρ0, a00(1450)ω, their branching ratios are close to each other between two scenarios, respectively. (c) Comparing with the decays B̄0 → π0ρ0, π0π0, the decay B̄0 → a00(1450)ρ0 receives a larger branching ratio in each scenario, which is sensitive to the variation of the Cabibbo—Kobayashi—Maskawa angle α.

In the two-quark model supposition for the meson a 0 (1450), which can be viewed as either the first excited state (scenario I) or the lowest lying state (scenario II), the branching ratios and the direct CP-violating asymmetries for decays B − → a − 0 (1450)φ and B0 → a 0 0 (1450)φ are studied by employing the perturbative QCD factorization approach. We find the following results. (a) If we do not consider the ω-φ mixing, the decays B − → a − 0 (1450)φ(s s) and B0 → a 0 0 (1450)φ(s s) are highly suppressed by the Okubo-Zweig-Iizuka rule; their branching ratios are at the order of 10 −9 in scenario I and even smaller in scenario II. (b) If the ω-φ mixing effect is included, the branching ratios can be dramatically enhanced, especially for the decay B0 → a 0 0 (1450)φ in scenario II, whose branching ratio arrives at the order of 10 −8 . In scenario I, the branching ratios are about a factor of 4-5 above the ones in the absence of ω-φ mixing. (c) For a more transparent comparison between the predictions and the data, we also calculate the ratioBecause it is less sensitive to the nonperturbative inputs, the large deviation of this ratio from the standard-model prediction could reveal a signal of new physics. (d) When the ω-φ mixing effect is included, the interference between the tree and the penguin contributions induces the direct CP violation, which is sensitive to the ω-φ mixing angle θ .
