Abstract

A search for the lepton family number violating decay D0→μe is reported. No signal is observed in a data sample of 9.3 pb-1 collected at the ζ (3770) resonance with the MARK III detector, where 0.18±0.06±0.05 background events are expected. A 90% confidence level upper limit on the branching fraction B(D0→μe) of 1.5 × 10-4 is obtained.
