Doubly Heavy Baryon Production in e⁺ e^? Annihilation

Considering the inclusive process, we study the doubly heavy baryon Ξ_cc (Ξ_bb) 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.
