First Measurement of the Lifetime of the Omega(c)0
by P.L. Frabetti et al.
We present the first measurement of the lifetime of the Omega_c^o baryon. The data were collected in the Fermilab high energy photoproduction experiment E687. The measured lifetime is $\tau = 86^{+27}_{-20} (stat) \pm 28 (sys) fs. Thus the Omega_c^o has one of the shorter lifetimes amoung the weakly decaying singly charmed baryons.
