Search for flavor-changing neutral current and Lepton-flavor violating decays of D0 --> (ell)+ (ell)-

Creators

Description

The authors 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 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 x 10-6 for D0 --> e+e-, 1.3 x 10-6 for D0 --> μ+μ-, and 8.1 x 10-7 for D0 --> e±μ±
