The results of several studies of charmed mesons and baryons at BABAR are presented. First, searches for the rare decays D 0 → l + l − are presented and new upper limits on these processes are established. Second, a measurement of the branching fraction of the isospin-violating hadronic decay D * s (2112) + → D + s π 0 relative to the radiative decay D * s (2112) + → D + s γ is made. Third, the decays of D * sJ (2317) + and D sJ (2460) + mesons are studied and ratios of branching fractions are measured. Fourth, Cabibbo-suppressed decays of the Λ + c are examined and their branching fractions measured relative to Cabibbo-allowed modes. Fifth, the Ξ 0 c is studied through its decays to Ξ − π + and Ω − K + ; in addition to measuring the ratio of branching fractions for Ξ 0 c produced from the cc continuum, the uncorrected momentum spectrum is measured, providing clear confirmation of Ξ 0 c production in B decays. Table 1: The expected background, the number of observed events, the corresponding branching fraction upper limit at the 90% confidence level (preliminary), and the previous upper limit for each decay mode.
