Abstract

We report results from a study of the charmed double strange baryons Ω_c⁰ and Ω_c^*0 at Belle. The Ω_c⁰ is reconstructed using the Ω_c⁰ --> Ω^- π⁺ decay mode, and its mass is measured to be (2693.6 ± 0.3 +1.8 \atop -1.5) MeV/c². The Ω_c^*0 baryon is reconstructed in the Ω_c⁰ γmode. The mass difference M_Ωc^*0 - M_Ωc⁰ is measured to be (70.7 ± 0.9 +0.1 \atop -0.9) MeV/c². The analysis is performed using 673 fb^-1 of data on and near the Υ(4S) collected with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider.
