Abstract
We search for the flavor-changing neutral current decays D0to mu_s16mu- and D0to e_s16e-, and for the lepton-flavor violating decays D0to epm mump using 660 fb^-1 of data collected with the Belle detector at the KEKB asymmetric-energy e_s16e- collider. We find no evidence for any of these decays. We obtain significantly improved upper limits on the branching fractions: B(D0to mu_s16mu-)
