Implications of family nonuniversal Z' model on B → K*0(1430)Π decays.

Within the QCD factorization formalism, we study the possible impacts of the nonuniversal Z' model, which provides a flavor-changing neutral current at the tree level, on rare decays B → K*0 ( 1430) Π. Under two different scenarios, Scenerio-1 (SI) and Scenerio-2 (S2), for identifying the scalar meson K*0(1430), the branching ratios, CP asymmetries, and isospin asymmetries are calculated in both the standard model and the family nonuniversal Z' model. We find that the branching ratios and CP asymmetries are sensitive to weak annihilation. In the standard model, with ρA = 1 and φA ∈ [--30°, 30°], the branching ratios of S1 (S2) are smaller (larger) than the experimental data. Adding the contribution of the Z' boson in two different cases (Case I and Case II), for SI, the branching ratios are still far away from experiment. For S2, in Case II, the branching ratios become smaller and can accommodate the data; in Case I, although the center values are enhanced, they can also explain the data with large uncertainties. Similar conclusions are also reached for CP asymmetries. Our results indicate that S2 is more favored than SI, even after considering new physics effects. Moreover, if there exists a nonuniversal Z' boson, Case II is preferred. All results can be tested in the LHC-b experiment and forthcoming super-B factory. [ABSTRACT FROM AUTHOR]
