Ω_c and other charmed baryons revisited

The mass of the $\Omega^0_c$ baryon with quark content (ssc) is computed in a potential model whose parameters have been determined in 1981 by fitting the spectrum of heavy mesons. It is found in perfect agreement with a recent measurement at the CERN hyperon-beam experiment. The spectroscopy of other charmed baryons in potential models is briefly reviewed.
