Measurement of the branching fraction of the inclusive decay D⁰ → Φ X and of exclusive decays of D⁰ involving a K⁺Ki⁻ decay — Gerhard Leder and •Franz Mandl — Inst. f. High Energy Physics of OeAW, Vienna, Austria

By fully reconstructing events involving a D^(*) on the tagging side and a D⁰ stemming from a D^* decay on the signal side and by adopting a novel reconstruction method various decay channels of the D⁰ are measured. They comprise D⁰ → Φ X, K⁺K⁻, Φ K⁰, (K⁺K⁻K⁰)_nonres, K⁺K⁻π⁰ and Φρ⁰. All branching fractions obtained (preliminary results) have a significance similar to and and are compatible with the newest PDG update.
