Abstract
Based on the assumption of a two-quark structure of the scalar K*0(1430), the CP-averaged branching ratios (BRs) and CP-violating asymmetries of non-leptonic decays are studied in two scenarios, namely scenario 1 and scenario 2, for the light-cone distribution amplitudes of the K*0(1430) meson in the standard model, by employing the perturbative QCD (pQCD) approach. Our predictions are the following: (1) the CP-averaged BRs for decays in both scenarios vary in the range of 10−6 ∼ 10−4 in the standard model; (2) the magnitudes of and AdirCP(Bd/s → K*0(1430)+K0*(1430)−) in scenario 1 are much larger than the corresponding magnitudes in scenario 2; (3) there are no direct CP violations in decays in the standard model because of the involved pure penguin topology. An experimental confirmation of our pQCD predictions at the predicted level will favor the structure of the scalar K*0(1430) and help us to understand its physical properties and the QCD dynamics involved.
