摘　　要：The two-body weak decays B→πD/B→ρD and B→πD are examined using isospin analysis to study nonfactorizable contributions.After determining strong interaction phases and obtaining factorizable contributions from spectator-quark diagrams for Nc=3,we determine nonfactorizable isospin amplitudes from the experimental data for these modes.Our results support the universality of the ratio of nonfactorizable isospin reduced amplitudes for these decays within experimental errors.To demonstrate that these systematics are not coincidental,we also plot our results w.r.t.this ratio.
