D. Pripstein et al., Search for flavor-changing neutral currents and lepton-family-number violation in two-body D-0 decays - art. no. 032005, PHYS REV D, 6103(3), 2000, pp. 2005
We present the results of a search for the three neutral charm decays D-0--
>mu(+/-)e(-/+), D-0 --> mu(+)mu(-), and D-0 --> e(+)e(-). This study was ba
sed on data collected in Experiment 789 at the Fermi National Accelerator L
aboratory using 800 GeV/c proton-Au and proton-Be interactions. No evidence
is found for any of the decays. Upper limits on the branching ratios, at t
he 90% confidence level, of 1.56 x 10(-5) for D-0-->mu(+)mu(-), 8.19 x 10(-
6) for D-0-->e(+)e(-) and 1.72 x 10(-5) for D-0-->mu(+/-)e(-/+) are obtaine
