“…Form-factor CLFQM [27] CLFQM [35] LQCD [37] A We wish to remark that similar observations have also been made in the FAT approach [23] analysis used for Bmeson decays, which separates the factorizable and nonfactorizable contributions in each topological quark level diagram. The most important result in this approach is that the non-perturbative parameters and , representing the nonfactorizable contributions, are found to be universal for all the decay modes, which is consistent with the systematics recognized in our analysis.…”

Two-body weak decays / and are examined using isospin analysis to study nonfactorizable contributions. After determining the strong interaction phases and obtaining the factorizable contributions from the spectator-quark diagrams for Nc=3, we determine nonfactorizable isospin amplitudes from the experimental data for these modes. Our results support the universality of ratio of nonfactorizable isospin reduced amplitudes for these decays within experimental errors. In order to show that this systematics is not coincidental, we also plot our results w. r. t. this ratio.
