Abstract
We present a search for seven lepton-flavor-violating neutral charm meson decays of the type D0→X0e±μ∓, where X0 represents a π0, K0S, ¯K*0, ρ0, ϕ, ω, or η meson. The analysis is based on 468 fb−1 of e+e− annihilation data collected at or close to the Υ(4S) resonance with the BABAR detector at the SLAC National Accelerator Laboratory. No significant signals are observed, and we establish 90% confidence level upper limits on the branching fractions in the range (5.0−22.5)×10−7. The limits are between 1 and 2 orders of magnitude more stringent than previous measurements.
