Abstract Based on the quark model the cross section for the $e^+e^-\to Z^0/\gamma^*\to{\it \Omega}_{ccc}^{++}\bar{\it \Omega}_{ccc}^{--}$ exclusive process is investigated at the tree level. Compared with the $ Z^0\to{\it \Omega}^{-}\bar{\it \Omega}^{+}$ 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.
