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-K?0π+, Ξ0K?0, and ΛK?0K?0, 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+. ? 2018 authors.
