A coupled-channel model with πN, ρN, and J / N channels is developed to predict the π + N → J / + N cross sections. The J / -N interaction is parameterized in a form related to what has been predicted by the effective field theory approach and lattice QCD. The other interactions within the model are constrained by the decay width of J / → ρ + π and the total cross-sectional data of πN reactions. The calculated meson-baryon amplitudes are then used to predict the cross sections of the J / production on the deuteron target by including the contributions from the impulse term and the one-loop calculations of the final NN and J / N rescattering effects. Predictions of the dependence of the cross sections of π − + p → J / + n, γ + d → J / + n + p, and π + d → J / + p + p on the J / -N potentials are presented to examine the feasibility of experimental determinations of the J / -N interaction. Within the vector meson dominance model, we have also applied the constructed coupled-channel model to predict the γ + p → J / + p cross sections near the J / production threshold.

“…2 Present status of the elastic electro-and photo-production J/ψ data Many of the J/ψ photoproduction experiments have been performed at high invariant mass of the photon-proton system (W γ−p and low t or in the case of electroproduction at large center of mass energy s and low t (see Refs. [33,34,35,36,37,38,39,40,41,42]) and more recently at LHCb [43] (see right Fig. 1) and are usually considered as diffractive production.…”
