How to include exclusive $J/\psi$ production data in global PDF analyses

We compare the cross section for exclusive J/ψ photoproduction calculated at next-to-leading order (NLO) in the collinear factorization approach with HERA and LHCb data. Using the optimum scale formalism together with the subtraction of the low kt contribution (below the input scale Q0) from the NLO...
