Inclusive Studies of D-Meson Decays at the ψ(3772)

We have measured charged multiplicities, inclusive branching ratios to states containing kaons, and average energy fractions in charged and neutral particles for decays of D mesons produced at the ψ(3772) resonance. The average charged multiplicity is 2.3+/-0.3 for both the neutral and the charged D. We find inclusive branching ratios B(D⁰-->K^+/-X)=0.35+/-0.10 and B(D⁺-->K^-X)=0.10+/-0.07 for decays into charged kaons.
