Measurement of the Omega0(c) lifetime

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