Abstract：
Within the framework of the perturbative QCD approach, we calculate the time-like B_cm B_c(B_c^*) form factors F(Q²) and A₂(Q²). We include relativistic corrections and QCD corrections, either of which can give about 20% correction to the leading-order contribution, but there are cancellation effects between them. We calculate the cross sections of the e⁺e^-→ B_c^- B_c⁺(B_c^*+) processes. The cross sections are enhanced at the Z pole to be σ^PP (Q=m_Z)~1.3×10^-5 pb and σ^PV (Q=m_Z)~2.5×10^-5 pb, which are still too small to be detected by proposed e⁺e^- colliders such as the Circular Electron Positron Collider.
