Description
In the talk we discuss NLO QCD corrections to total inclusive J/ψ and Υ photoproduction cross sections in lepton-proton collisions at the EIC, where the resulting cross sections
obtained in the MS factorisation scheme are sometimes found to be negative. It is shown that the scale-fixing criteria which was derived in a previous study of ηc production successfully
solves this problem from the EicC all the way up to the FCC-eh energies. We also discuss where both J/ψ and Υ photoproduction could be used to improve our knowledge of gluon content of the proton at scales as low as a couple of GeV.
