摘要：

We present the first measurement of the lifetime of the Omega(c)(0) baryon. The data were collected in the Fermilab high energy photoproduction experiment E687. The measured lifetime is tau = 86(-20)(+27)(stat.) +/- 28(syst.) fs. Thus the Omega(c)(0) has one of the shorter lifetimes among the weakly decaying singly charmed baryons.
