| dc.description | Production and decay of $Ω_c^0$ baryons is studied with $\sim230 \mathrm{fb}^{-1}$ of data recorded with the BABAR detector at the PEP-II $e^+e^-$ asymmetric-energy storage ring at SLAC. The $Ω_c^0$ is reconstructed through its decays into $Ω^-π^+$, $Ω^-π^+π^+π^-$, and $Ξ^-K^-π^+π^+$ final states. The invariant mass spectra are presented and the signal yields are extracted. Ratios of branching fractions are measured relative to the $Ω^-π^+$ mode \frac{{\cal B}(Ξ^-K^-π^+π^+)}{{\cal B}(Ω^-π^+)} &= 0.31 \pm 0.15\mathrm{(stat.)} \pm 0.04\mathrm{(syst.)}, \frac{{\cal B}(Ω^-π^+π^+π^-)}{{\cal B}(Ω^-π^+)} &< 0.30\qquad (90%\mathrm{CL}). The momentum spectrum (not corrected for efficiency) of $Ω_c^0$ baryons is extracted from decays into $Ω^-π^+$, establishing the first observation of $Ω_c^0$ production from B decays. | |
