英文摘要:
By assuming that the scalar meson K-0*(1430) belongs to the first excited states or the lowest lying ground states of q (q) over bar' we study the pure annihilation-type decays B -> K-0*(+/-)(1430)K-(*)-/+ in the QCD factorization approach. Within the Standard Model, the branching fractions are of the order of 10(-8)-10(-7), which is possible to measure in the ongoing LHCb experiment or forthcoming Belle-II experiment. We also study these decays in the family non-universal Z' model. The results show that if m(z') approximate to 600 GeV (zeta = 0.02), both the branching fractions and CP asymmetries of (B) over bar (0) -> K-0*(+)(1430)K- could be changed remarkably, which provides us with a place for probing the effect of new physics. These results could be used to constrain the parameters of the Z' model.
