Abstract

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 mesons through the Z ⁰ boson decays, where uncertainties for the production are also discussed. Our results show  KeV and  KeV, where the errors are caused by varying m _b and m _c within their reasonable regions.
