Description:
Motivated by the powerful capability of measurement for the hadron decays at LHC and SuperKEKB/Belle-II, the nonleptonic , , , , and decays are studied. With the amplitudes calculated with factorization approach and the form factors evaluated with the BSW model, branching fractions and polarization fractions are firstly presented. Numerically, the CKM-favored and decays have branching fractions ~10−8, which should be sought for with priority and firstly observed by LHC and Belle-II. The and decays are dominated by the longitudinal polarization states, while the parallel polarization fractions of decays are comparable with the longitudinal ones; numerically, + 95% and . Some comparisons between and their corresponding decays are performed, and the relation is found. With the implication of flavor symmetry, the ratios and are discussed and suggested to be verified experimentally.
