Z-boson decay provides a good opportunity to search for the $ \Xi_{bQ} $ 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 $ \Xi_{bQ} $ and $ \Xi_{bQ} $ baryons via the Z-boson decay process $ \Xi_{bQ} $ with a $ \Xi_{bQ} $ quark under the NRQCD factorization approach. After considering the contribution from the diquark states $ \Xi_{bQ} $ , $ \Xi_{bQ} $ , $ \Xi_{bQ} $ , and $ \Xi_{bQ} $ , the calculated branching fractions are $ \Xi_{bQ} $ and $ \Xi_{bQ} $ . Furthermore, the $ \Xi_{bQ} $ and $ \Xi_{bQ} $ production events are predicted to be of the order of $ \Xi_{bQ} $ and $ \Xi_{bQ} $ at the LHC collider, and the order of $ \Xi_{bQ} $ and $ \Xi_{bQ} $ for the CEPC collider. We then estimate the production ratio for $ \Xi_{bQ} $ with $ \Xi_{bQ} $ in Z-boson decay, that is, $ \Xi_{bQ} $ and $ \Xi_{bQ} $ , respectively. Finally, we present the differential decay widths of $ \Xi_{bQ} $ and $ \Xi_{bQ} $ with respect to $ \Xi_{bQ} $ and z distributions and analyze the uncertainties.
