摘要：
The resonant contributions in the decays (B) over bar (0)((s)) -> D-0 pi(+)pi(-), (B) over bar (0)((s)) -> (DK+)-K-0 K-, and (B) over bar -> D-0 pi(0)eta are investigated by considering the final state interactions within the chiral unitary approach, where the scalar resonances f(0)(500), f(0)(980), and a(0)(980) are dynamically generated from the final state interactions. In addition, the vector mesons rho, phi and D-0*(2300) directly produced in p wave are also taken into account. From the invariant mass distributions of B-0 decays, it is found that the contributions of f(0)(500) and a(0)(980) are remarkably larger than those of f(0)(980). However, for the case of B-s(0) decays only a clear structure close to the K+ K- threshold appears, which corresponds to the f(0)(980) state and has no signal for the f(0)(500) resonance. For the decay (B) over bar (0)((s)) -> (DK+)-K-0 K-, the K+ K- invariant mass distributions are consistent with the experimental data up to 1.1 GeV, and the dominant contributions come from the vector meson phi. Moreover, the branching fractions and the ratios of branching fractions are also studied, some of which are compatible with the experimental measurements. The branching fraction Br((B) over bar (0) -> D(0)a(0)(980)[a(0)(980) -> pi(0) eta]) = (6.08 +/- 0.72) x 10(-5) and the ratio of branching fractions Br((B) over bar (0) -> D-0 f(0)(980))/Br((B) over bar (0) -> D(0)a(0)(980)) = 0.13 +/- 0.03 are predicted.
