英文摘要	The production of B-c and B-c* mesons at a Z-factory (an e(+)e(-) collider operating at energies around the Z pole) is calculated up to the next-to-leading order (NLO) QCD accuracy. The results show that the dependence of the total cross sections on the renormalization scale it is suppressed by the corrections, and the NLO corrections enhance the total cross sections of B-c by 52% and of B-c* by 33% when the renormalization scale is taken at mu = 2m(b). To observe the various behaviors of the production of the mesons B-c and B-c*, such as the differential cross section vs. the out-going angle, the forward-backward asymmetry, and the distribution vs. the energy fraction z up to NLO QCD accuracy as well as the relevant K-factor (NLO to LO) for the production, are calculated, and it is pointed out that some of the observables obtained in the present work may be used as a specific precision test of the standard model.
