摘　　要：Based on the quark model the cross section for the e^(+)e^(-)→Z^(0)/r^(*)→Ω^(++)_(ccc)Ω^(--)_(ccc)exclusive process is investigated at the tree level.Compared with the Z^(0)→Ω^(-)Ω^(+)decay,our result shows that the Z^(0)boson favors decaying into charmed baryon pairs.The results are also compared with the calculation of inclusively charmed baryon production.
