Abstract

Within the framework of the perturbative QCD approach based on kT factorization, we investigate the charmless decay mode B→K0*(1430). Under two different scenarios (S1 and S2) for the description of scalar meson K0*(1430), we explore the branching fractions and related CP asymmetries. Besides the dominant contributions from the factorizable emission diagrams, penguin operators in the annihilation diagrams could also provide considerable contributions. The central values of our predictions are larger than those from the QCD factorization in both scenarios. Compared with the experimental measurements of the BaBar Collaboration, the result of the neutral channel in the S1 agrees with experimental data, while the result of the charged one is a bit smaller than the data. In the S2 scenario, although the central value for the branching fractions of both channels is much larger than the data, the predictions could agree with the data due to the large uncertainties to the branching fractions from the hadronic input parameters. The CP asymmetry in the charged channel is small and not sensitive to the Cabibbo-Kobayashi-Maskawa angle γ. With accurate data in the near future from the various B factories, these predictions will be under stringent tests.
