| 摘 要： | Z-boson decay provides a good opportunity to search for the ΞbQ baryon because a large number of its events can be collected at high energy colliders.In this paper,we perform a complete investigation of the indirect production of the Ξbc and Ξbb baryons via the Z-boson decay process Z→ΞbQ+■+■ with a Q=(c,b) quark under the NRQCD factorization approach.After considering the contribution from the diquark states ■,■ and ■,the calculated branching fraction...
