Abstract:Considering the inclusive process, we study the doubly heavy baryon Ξcc (Ξbb) production through e+ e? annihilation. Both the diquark QQ in color sextet and triplet are discussed. The results show that the contributions from these two color states play equally important roles. At the Z0 pole, a significant enhancement can be found in the doubly heavy baryon production.
