| Abstract: | We investigate nonfactorizable contributions to charm meson decays in $D \to \bar K\pi /\bar K\rho /\bar K*\pi /\bar Ka_1 /\bar K*\rho $ modes. Obtaining the contributions from spectator-quark diagrams forN c=3, we determine nonfactorizable isospin 1/2 and 3/2 amplitudes required to explain the data for these modes. We observe that ratio of these amplitudes seem to follow a universal value. |
