B \to K_0^*(1430) η^{(\prime)} decays in the pQCD approach

Abstract

Based on the assumption of two-quark structure of the scalar meson $K_0^{\ast }(1430)$, we calculate the CP-averaged branching ratios for $B \to K_0^*(1430) \etap$ 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 $Br(B\to K_0^{\ast }(1430){\eta }^{(\prime )})$ is $10^{-5}-10^{-6}$, basically agree with the data within large theoretical uncertainty; (b) the agreement between the pQCD predictions and the data in the scenario I is better than that in the scenario II, which can be tested by the forthcoming LHC experiments; (c) the annihilation contributions play an important role for these considered decays.
