摘要：
An analysis is presented measuring the production rate of the strange baryon Xi(c)(0) in the exclusive decay channel C Xi(c)(0) --> Xi(-)pi(+), to be f(Xic)0 x BR(Xi(c)(0) --> Xi(-)pi(+)) = (4.7 +/- 1.4(stat) +/- 1.1(syst)) x 10(-4). A measurement of the production rate of the beauty strange baryon Xi(b) is also presented, using the inclusive channel Xi(b) --> Xi(-)l(-)X. The measured production rate was BR(b--> Xi(b)) x BR(Xi(b) --> Xi(-)l(-)X) = (6.0 +/- 1.9(stat) +/- 0.8(syst)) x 10(-4) per lepton species.
