Abstract

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 (D^{0} \to K^{\pm} X) = 0.35 \pm 0.10

and

B (D^{+} \to K^{-} X) = 0.10 \pm 0.07

for decays into charged kaons.
