B→K₀^*(1430) η^(′) decays in the pQCD approach

Abstract: 

Based on the assumption of two-quark structure of the scalar meson K₀^*(1430), we calculate the CP-averaged branching ratios for B→K₀^*(1430) η^(′) decays in the framework of the perturbative QCD (pQCD) approach here. We perform the evaluations in two scenarios for the scalar meson spectrum. We find that: (a) the pQCD predictions for Br(B→K₀^*(1430) η^(′)) which are about 10^－5−10^－6, basically agree with the data within large theoretical uncertainty; (b) the agreement between the pQCD predictions and the data in Scenario I is better than that in Scenario II, which can be tested by the forthcoming LHC experiments; (c) the annihilation contributions play an important role for these considered decays.
