摘要：

Based on the assumption of two-quark structure of the scalar meson K-0*(1430), we calculate the CP-averaged branching ratios for B --> K-0*(1430)eta(()'()) decays in the framework of the perturbative QCD (pQCD) approach here. We perform the evaluations in two scenarios for the scalar meson spectrum. We find that: (a) the pQCD predictions for Br(B --> K-0*(1430)eta(()'())) which are about 10(-5)-10(-6), basically agree with the data within large theoretical uncertainty: (b) the agreement between the pQCD predictions and the data in Scenario I is better than that in Scenario II, which can be tested by the forthcoming LHC experiments; (c) the annihilation contributions play an important, role for these considered decays.
