Measurement of Branching Fractions of Hadronic Decays of the ${\mathrm{\Omega }}_c^0$ Baryon

Using a data sample of 980 ${\mathrm{f}\mathrm{b}}^{-1}$ 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 ${\mathrm{\Omega }}_c^0$ charmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the ${\mathrm{\Omega }}_c^0$ into ${\mathrm{\Omega }}^{-}{\pi }^{+}{\pi }^0$, ${\mathrm{\Omega }}^{-}{\pi }^{+}{\pi }^{-}{\pi }^{+}$, ${\mathrm{\Xi }}^{-}{K}^{-}{\pi }^{+}{\pi }^{+}$, and ${\mathrm{\Xi }}^0{K}^{-}{\pi }^{+}$, as well as the first measurements of the branching fractions of the ${\mathrm{\Omega }}_c^0$ into ${\mathrm{\Xi }}^{-}{\bar{K}}^0{\pi }^{+}$, ${\mathrm{\Xi }}^0{\bar{K}}^0$, and $\Lambda \bar{K}^0\bar{K}^0$,allwithrespecttothe$\Omega^-\pi^+$ decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay ${\mathrm{\Omega }}_c^0\to {\mathrm{\Sigma }}^{+}{K}^{-}{K}^{-}{\pi }^{+}$.
