Аннотация:We present theoretical analysis of paired BcBc mesons production in e+e− annihilation at different energy scales taking into account full next-to-leading order QCD corrections. Both possible electroweak channels are considered: production via virtual photon and via virtual Z-boson. We study in detail the role of radiative QCD corrections, which were found to be significant especially at low energies. It is shown that the contribution from Z -boson is significant at high energies (View the MathML sources>MZ/2) especially in the case of paired production of pseudo-scalar and vector (View the MathML sourceBc+Bc⁎) mesons. Azimuthal asymmetry induced by a P-violating weak interaction with Z-boson is also analyzed.
