Popis:	We discuss J/ψ ηc production in e + e − annihilation at next-to-leading order of pQCD. We are focusing at virtual Z 0 contribution into this process: the interference between virtual photon and Z 0-boson is required for careful study. Cross-sections behavior at high energies is studied. At energies ~ M Z0 the NLO contribution enhances cross-sections up to 2 times.
