Production and decay of Omega_c0 baryons is studied with
~230 fb-1 of data recorded with the BABAR detector
at the PEP-II e+e- asymmetric-energy storage ring at SLAC. The
Omega_c0 is reconstructed through its decays into Omega- pi+, 
Omega- pi+ pi+ pi-, and Xi- K- pi+ pi+ final states. 

The invariant mass spectra are presented and the signal yields are
extracted. Ratios of branching fractions are measured relative to the
Omega- pi+ mode

  B(Xi- K- pi+ pi+)
  ----------------- = 0.31 +- 0.15(stat.) +- 0.04(syst.),\
    B(Omega- pi+)     

  B(Omega- pi+ pi+ pi-)
  --------------------- < 0.30 (90%CL)
      B(Omega- pi+)     

The momentum spectrum (not corrected for efficiency) of Omega_c0
baryons is extracted from decays into Omega- pi+, establishing the
first observation of Omega_c0 production from B decays.
