[en] We present theoretical analysis of paired mesons production in 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 () especially in the case of paired production of pseudo-scalar and vector () mesons. Azimuthal asymmetry induced by a P-violating weak interaction with Z-boson is also analyzed.
