- Abstract
Using a data sample of 980 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 Ωc⁰ charmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the Ωc⁰ into Ω⁻π⁺π⁰, Ω⁻π⁺π⁻π⁺, Ξ⁻K⁻π⁺π⁺, and Ξ⁰K⁻π⁺, as well as the first measurements of the branching fractions of the Ωc⁰ into Ξ⁻K̄⁰π⁺, Ξ⁰K̄⁰, and ΛK̄⁰K̄⁰, all with respect to the Ω⁻π⁺ decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay Ωc⁰ → Σ⁺K⁻K⁻π⁺.
