Abstract

We present theoretical analysis of paired BcB_c mesons production in e+ee^+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 ZZ-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 ZZ-boson is significant at high energies (s>MZ/2\sqrt{s} > M_Z/2) especially in the case of paired production of pseudo-scalar and vector (Bc+BcB_c + B_c^*) mesons. Azimuthal asymmetry induced by a PP-violating weak interaction with ZZ-boson is also analyzed.
