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.
