Abstract

Using a data sample of 980fb1 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 Ωπ+π0, Ωπ+ππ+, ΞKπ+π+, and Ξ0Kπ+, as well as the first measurements of the branching fractions of the Ωc0 into ΞK¯0π+, Ξ0K¯0, and ΛK¯0K¯0, all with respect to the Ωπ+ decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay Ωc0Σ+KKπ+.
