The FOCUS experiment (FNAL-E831) has used two channels, Ω-π+ and Ξ-K-π+π+, to measure the lifetime of the Ω0c charmed baryon. From a sample of 64 ± 14 signal events at a mass of 2.698 GeV/c2, we measure an Ω0c lifetime of 72 ± 11 (stat.) ± 11 (sys.) fs, substantially improving upon the current world average.
