First evidence of Omega(c)0 --> Omega(-) pi(+)
by P.L. Frabetti et al.
Abstract.
We report evidence of a narrow resonance at a mass of
$2705.9 \pm 3.3 \pm 2.0$ MeV/c$^2$ in the final state $\Omega^-
\pi^+$ and the charge conjugate.
The mass and width
support the interpretation of a weakly decaying
doubly strange charmed baryon, the $\Omega_c^0$. Limits on the relative
branching
ratios for $\Omega_c^0 \rightarrow \Xi^- K^-\pi^+\pi^+$ and
$\Omega_c^0\rightarrow \Omega^- \pi^-\pi^+\pi^+$ are also presented.
