We present the results of a search for the three neutral charm decays D0→μ±e∓, D0→μ+μ-, and D0 →e+e-. This study was based on data collected in Experiment 789 at the Fermi National Accelerator Laboratory 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 the 90% confidence level, of 1.56×10-5 for D0→μ+μ-, 8.19 ×10-6 for D0→e+e- and 1.72×10-5 for D0→μ±e∓ are obtained.
