Abstract:
Using data collected by the Fermilab experiment FOCUS, we measure the lifetime of the charmed baryon Xi_c^0 using the decay channels (Xi_c^0 -> Xi- pi+) and (Xi_c^) -> Omega- K+). From a combined sample of (110 +/- 17) events we find (tau(Xi_c^0) = ~118^{+ 14}_{- 12} +/- 5) fs, where the first and second errors are statistical and systematic, respectively.
