Search for Flavor-Changing Neutral Current and Lepton-Flavor Violating Decays of D[superscript 0]-->l+l-
We report on a search for the flavor-changing neutral current decays D0→e+e- and D0→μ+μ-, and the lepton-flavor violating decay D0→e±μ∓. The measurement is based on 122 fb-1 of data collected by the BABAR detector at the SLAC PEP-II asymmetric e+e- collider. No evidence is found for any of the deca...

| description | We report on a search for the flavor-changing neutral current decays D0→e+e- and D0→μ+μ-, and the lepton-flavor violating decay D0→e±μ∓. The measurement is based on 122 fb-1 of data collected by the BABAR detector at the SLAC PEP-II asymmetric e+e- collider. No evidence is found for any of the decays. The upper limits on the branching fractions, at the 90% confidence level, are 1.2×10-6 for D0→e+e-, 1.3×10-6 for D0→μ+μ-, and 8.1×10-7 for D0→e±μ∓. |
