Abstract

Based on a dataset acquired by the BaBar experiment running on and near the Υ(4S) resonance from 1999-2002, limits are set on the rate of D⁰-- \kern 0.2em\kern -0.2em D⁰ mixing using the decay mode D^*+ → D⁰ π⁺, followed by a semi-leptonic decay of the D⁰. Results are compared to previous BaBar analysis using hadronic decays. We also report on a search for the flavor-changing neutral current decays D⁰ → e⁺ e^- (μ⁺ μ^-) and the lepton-flavor violation decays D⁰ → e^± μ^∓.
