Abstract

We report a revised determination of charmed-D-meson absolute branching fractions based on complete reconstruction of DD» events at the (3770). Two backgrounds, Cabibbo-suppressed and multi-0 D decays, are addressed in detail. The first measurement of the decay D0K-+00 establishes the sensitivity to hitherto unobserved multi-0 modes. Removal of both backgrounds reduces the values of our previously reported branching fractions by (21-24)%, leaving their ratios largely unchanged. The new values are unable to account fully for a reported deficit in charm production in B-meson decay.
