Abstract

We report evidence of a narrow resonance at a mass of 2705.9 ± 3.3 ± 2.0 MeV/c2 in the final state Ω-π+ and the charge conjugate. The mass and width support the interpretation of a weakly decaying doubly strange charmed baryon, the Ωc0. Limits on the relative branching ratios for Ωc0→Ω-K-π+π+ and Ωc0→Ω-π-π+π+ are also presented.
