Photoproduction constraints on J/psi-nucleon interactions
K. Redlich, H. Satz, G. M. Zinovjev
Abstract
Using J/psi and open charm photoproduction data, we apply the vector meson dominance model to obtain constraints on the energy dependence of the inelastic J/psi-nucleon cross section. Predictions of short distance QCD are in accord with these constraints, while recently proposed hadronic models for J/psi dissociation strongly violate them.
