Based on the assumption of two-quark structure of the scalar meson K*0(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...

One outstanding question is the extent to which the precision on quark masses, especially mc/mb, can be improved. If one assumes that new physics is not present, the method can be used to predict the values of CP asymmetries in Bd0→K0K̅ 0: 0.02≤Adir2+Amix2≤0.125. A result out...
We investigate B→K0*(1430)K* decays in the perturbative QCD (pQCD) factorization approach, where B denotes Bu, Bd, and Bs mesons, respectively, and the scalar K0*(1430) is considered as a meson based on the model of the conventional two-quark structure. With the light-cone distribution...
