D-->PV decays with final state interactions

We employ one-particle-exchange method to study D-->PV decays in D-->K \rho, \pi K*, \pi \rho processes. Taking into account a strong phase and considering nonfactorizable effect, we can get good results consistent with the experimental data. Nonfactorizable effect is not always large, but in some cases, the nonfactorizable effect is nececcesary to accommodate the experimental data. Strong phase is approximately SU(3) flavour symmetric.
