Dº decays from e+e- collisions: precision, rare and substructure results

Three analyses of D0 meson decays are presented which use the data collected with the CLEO II detector at the Cornell Electron Storage Ring. First, a precision measurement of the ratio of the Dº → K-π+πº branching fraction to that of Dº → K-π+ is performed resulting in the best measurement to date. Second, a detailed high statistics study of the underlying resonant structure of the three body decay, Dº → K-π+πº, is carried out. The resulting Dalitz plot is well fi t by the inclusion of seven resonances, along with a non-resonant three body decay component. Finally a search for the radiative decays of the Dº meson is presented along with the four upper limits obtained.
