摘要： Two-body weak decays of bottom mesons into two pseudoscalar mesons are examined employing SU(3) flavor symmetry for the nonfactorizable matrix elements. Using certain measured Cabibo-favored modes, we fix the reduced matrix elements and predict the branching ratios of the Cabibbo-angle favored and suppressed decays of B and Bs mesons.
