Study of Charm Baryons with the BaBar Experiment
We report on several studies of charm baryon production and decays by the BaBar collaboration. We confirm previous observations of the $\Xi_c^{'0/+}$, $\Xi_c(2980)^+$ and $\Xi_c(3077)^+$ baryons, measure branching ratios for Cabibbo-suppressed $\Lambda_c^+
