Abstract

We present a measurement of the inclusive branching fractions for the decays D + [arrow right] Xe + ν e and D 0 [arrow right] X e + ν e , using 281 pb -1 of data collected on the ψ(3770) resonance with the CLEO-c detector. We find [Special characters omitted.] ( D 0 [arrow right] X e + ν e ) = (6.46 ± 0.17 ± 0.13)% and [Special characters omitted.] ( D + [arrow right] X e + ν e ) = (16.13 0.20 ± 0.33)%.
