摘要：

Using data taken at the Fermilab FOCUS experiment (FNAL-E831), we have measured the lifetimes of the single charm baryons: Lambda(c)(+),Xi(c)(+),Xi(c)(0). A preliminary lifetime measurement of the Omega(c)(0) charm baryon will be presented. We also report our measurements of branching ratios for some Lambda(c)(+) decay modes and in particular the first measurement of the relative branching ratio for the Cabibbo suppressed decay mode Lambda(c)(+) --> Sigma(+)K*(892) with respect to the Lambda(c)(+) --> Sigma(+)pi(+)pi(-) mode and an upper limit for the Cabibbo suppressed decay Lambda(c)(+) --> Sigma(-)K(+)pi(+). Finally our search of the double charm baryons will be presented.
