N2 - We search for rare FCNC charm decays of the form $X_c^+\to h^+\llp$, where X+c is a charm hadron, h is a pion, kaon or proton, and ℓ(′) is an electron or a muon. In the pion and kaon modes, we study both D+ and D+s decays, while in the proton modes we study Λ+c decays. Based on a data sample of 288fb−1 of e+e− collisions collected by BABAR, we set preliminary 90% confidence level limits between 4 to 40×10−6 for the branching fractions of the different decay modes. For most decay modes, our analysis provides a significant improvement over previous results.
