Search for Rare and Forbidden Decays of D0->l+l-
- SLAC
We report on a search for the flavor-changing neutral current decays D{sup 0} {yields} e{sup +}e{sup -} and D{sup 0} {yields} {mu}{sup +}{mu}{sup -}, and the lepton-flavor violating decay D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}. The measurement is based on 122fb{sup -1} of data collected by the BABAR detector at the PEP-II asymmetric e{sup +}e{sup -} 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 x 10{sup -6} for D{sup 0} {yields} e{sup +}e{sup -}, 1.3 x 10{sup -6} for D{sup 0} {yields} {mu}{sup +}{mu}{sup -}, and 8.1 x 10{sup -7} for D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}.
