Abstract

The programming new e+ee^{+}e^- collider with high luminosity shall provide another useful platform to study the properties of the doubly heavy BcB_c meson in addition to the hadronic colliders as LHC and TEVATRON. Under the `New Trace Amplitude Approach', we calculate the production of the spin-singlet BcB_c and the spin-triplet BcB^*_c mesons through the Z0Z^0 boson decays, where uncertainties for the production are also discussed. Our results show Γ(1S0)=81.440.5+102.1\Gamma_{(^1S_0)}= 81.4^{+102.1}_{-40.5} KeV and Γ(3S1)=116.462.8+163.9\Gamma_{(^3S_1)}=116.4^{+163.9}_{-62.8} KeV, where the errors are caused by varying mbm_b and mcm_c within their reasonable regions.
