Abstract
The processes of a light neutral vector meson, V=ρ^0, ω, ϕ, electroproduction and a heavy quarkonium, V=J/Ψ, Υ, photoproduction are studied in the framework of QCD factorization. We derive a complete set of hard-scattering amplitudes which describe these processes at next-to-leading order (NLO).
