Study of Ω_c^0 and Ω_c^{*0} Baryons at Belle

Abstract

We report results from a study of the charmed double strange baryons Ω_c^0 and Ω_c^{*0} at Belle. The Ω_c^0 is reconstructed using the Ω_c^0 --> Ω^- π^+ decay mode, and its mass is measured to be (2693.6 \pm 0.3 {+1.8 \atop -1.5}) MeV/c^2. The Ω_c^{*0} baryon is reconstructed in the Ω_c^0 γmode. The mass difference M_{Ω_c^{*0}} - M_{Ω_c^0} is measured to be (70.7 \pm 0.9 {+0.1 \atop -0.9}) MeV/c^2. 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.
