摘要：
The planned new e (+) e (-) collider with high luminosity shall provide another useful platform to study the properties of the doubly heavy B (c) meson in addition to the hadronic colliders as LHC and TEVATRON. In the 'New Trace Amplitude Approach', we calculate the production of the spin-singlet B (c) and the spin-triplet B*(c) mesons through the Z(0) boson decays, where uncertainties for the production are also discussed. Our results show Gamma (S-1(0)) = 81.4(-40.5)(+102.1) KeV, and Gamma (S-3(1)) = 116.4(_-62.8)(+163.9) KeV, where the errors are caused by varying m (b) and m (c) within their reasonable regions.
