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

Abstract

Using a data sample of 980 ${\mathrm{fb}}^{-1}$ 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 ${\Xi }^0{K}^{-}{\pi }^{+}$, 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 ${\Omega }_c^0\to {\Sigma }^{+}{K}^{-}{K}^{-}{\pi }^{+}$.
