We study inclusive J/ψ photoproduction at NLO at large PT at HERA and the EIC. Our computation includes NLO QCD leading-PT corrections, QED contributions via an off-shell photon as well as those from J/ψ+charm channels. For the latter, we employ the variable-flavournumber scheme. Our results are found to agree with the latest HERA data by H1 and provide, for the first time, a reliable estimate of the EIC reach for such a measurement. Finally, we demonstrate the observability of J/ψ+charm… Expand
