摘要
Within the framework of the perturbative QCD approach, we calculate the time-like BcBc(B-c*) form factors F(Q(2)) and A(2) (Q(2)). 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(-) -> Bc-Bc+(B-c*(+)) processes. The cross sections are enhanced at the Z pole to be sigma(PP) (Q =mz) similar to 1.3 x10(-5) pb and sigma(PV) (Q=mz) similar to 2.5 x 10(-5) pb, which are still too small to be detected by proposed e(+)e(-) colliders such as the Circular Electron Positron Collider.
