First evidence of omega(c)0 ---> omega- pi+

Journal Article · · Phys.Lett.B
We report evidence of a narrow resonance at a mass of 2705.9 ± 3.3 ± 2.0 MeV/ c 2 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 Ω c 0 . Limits on the relative branching ratios for Ω c 0 →Ω – K – π + π + and Ω c 0 →Ω – π – π + π + are also presented.
