| 英文摘要 | 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 nonleptonic B-u/d/s -> K-0* (1430) (K) over bar (0)* (1430) 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 B-u/d/s -> K-0* (1430) (K) over bar (0)* (1430) decays in both scenarios vary in the range of 10(-6) similar to 10(-4) in the standard model; (2) the magnitudes of A(CP)(dir) (B-u -> K-0* (1430) + (K) over bar (0)* (1430)(0)) and A(CP)(dir) (B-d/s -> K-0* (1430) + K-0* (1430)(-)) in scenario 1 are much larger than the corresponding magnitudes in scenario 2; (3) there are no direct CP violations in B-d/s -> K-0* (1430)(0)(K) over bar (0)* (1430)(0) 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 q (q) over bar structure of the scalar K-0* (1430) and help us to understand its physical properties and the QCD dynamics involved. |
