Abstract

We report evidence of a narrow resonance at a mass of 2705.9 ± 3.3 ± 2.0 MeV/c2 in the final state Omega−π+ and the charge conjugate. The mass and width support the interpretation of a weakly decaying doubly strange charmed baryon, the Omegac0. Limits on the relative branching ratios for Omegac0→Omega−K−π+π+ and Omegac0→Omega- pi−pi+pi+ are also presented.
