Abstract:
We report on a search for the flavor-changing neutral current decays \Dz\to e^+e^- and \Dz\to\mu^+\mu^-, and the lepton-flavor violating decay \Dz\to e^\pm\mu^\mp. The measurement is based on of data collected by the \babar detector at the PEP-II asymmetric collider. No evidence is found for any of the decays. The upper limits on the branching fractions, at the 90 % confidence level, are for \Dz\to e^+e^-, for \Dz\to\mu^+\mu^-, and for \Dz\to e^\pm\mu^\mp.- 11.30.Hv
