Photoproduction constraints on \(J/\psi\)-nucleon interactions
- 34 Downloads
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.
