Implications of exclusive $J/\psi$ photoproduction in a tamed collinear factorisation approach to NLO

We discuss exclusive $J/\psi$ photoproduction, initially in conventional collinear factorisation at NLO and then subsequently in a refined approach with a programme of low $x$ resummation and implementation of a crucial low $Q_0$ subtraction included. We compare and contrast predictions in both fram...
