- Аннотация: We discuss J/ψ ηc production in e+e− annihilation at next-to-leading order of pQCD. We are focusing at virtual Z0 contribution into this process: the interference between virtual photon and Z0-boson is required for careful study. Cross-sections behavior at high energies is studied. At energies ~ MZ0 the NLO contribution enhances cross-sections up to 2 times.
