By assuming that the scalar meson K0*（1430） belongs to the first excited states or the lowest lying ground states of qq’,we study the pure annihilation-type decays B→K0*（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 mZ≈600 GeV（ζ=0.02）,both the branching fractions and CP asymmetries of B0→K0+（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.

By assuming that the scalar meson K＊0 （1430） belongs to the first excited states or the lowest lying ground states of qq＇, 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 mZ＇≈600 GeV（ζ0.02）,both the branching fractions and CP asymmetries of -0B→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 Zj model.
