Abstract

We determine the resonant substructure of DK» decays, extracting the relative fractions and phases of the amplitudes contributing to the K-++-, K»0++-, K-++0, and K»0+-0 final states. We find that two-body decay modes account for at least 75% of these decays. We obtain branching ratios for DK»a1(1260), DK»* DK»1(1270), DK»1(1400), and D0'K»0 decay modes, as well as for several three- and four-body decay modes. In the case of DK»a1(1260) and DK»*, we obtain the branching ratios for all three possible isospin combinations, enabling us to extract the isospin- and -32 amplitudes, and their relative phases. We find that the isospin-32 amplitudes are suppressed relative to the isospin- amplitudes. This implies that the widths of the D+ modes are suppressed relative to those of the D0, confirming that an understanding of the lifetime difference of the D0 and D+ depends on an understanding of two-body hadronic decays. For the DK»* decay modes, we obtain detailed information on the polarization of the K»* and . This enables us to place constraints on the form factors for D'K»* and D transitions. A comparison of our results on D'K»* decays with recent results on semileptonic decays allows us to test the factorization hypothesis.
