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.
