摘要：

The FOCUS experiment (FNAL-E831) has used two channels, Omega(-)pi(+) and Theta(-)K(-)pi(+)pi(+), to measure the lifetime of the Omega(c)(0) charmed baryon. From a sample of 64 +/- 14 signal events at a mass of 2.698 GeV/c(2), we measure an Omega(c)(0) lifetime of 72 +/- 11 (stat.) +/- 11 (sys.) fs, substantially improving upon the current world average.
