Measurement of Branching Fractions of Hadronic Decays of the \(\Omega_c^0\) Baryon

Using a data sample of 980 \({\rm fb}^{-1}\) of \(e^+e^-\) annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy \(e^+e^-\) collider, we report the results of a study of the decays of the \(\Omega_c^0\) charmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the \(\Omega_c^0\) into \(\Omega^-\pi^+\pi^0\), \(\Omega^-\pi^+\pi^-\pi^+\), \(\Xi^-K^-\pi^+\pi^+\), and \(\Xi^0K^-\pi^+\), as well as the first measurements of the branching fractions of the \(\Omega_c^0\) into \(\Xi^-\bar{K}^0\pi^+\), \(\Xi^0\bar{K}^0\), and \(\Lambda \bar{K}^0\bar{K}^0\), all with respect to the \(\Omega^-\pi^+\) decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay \(\Omega_c^0\to\Sigma^+K^-K^-\pi^+\).
