Abstract: 
J/psi dissociation in collisions with nucleons is studied within a boson-exchange model and the energy dependence of the dissociation cross section is calculated from the threshold for Lambda (c)(D) over bar production to high energies. We illustrate the agreement of our results with calculations based on short-distance QCD and Regge theory. The compatibility between our calculations and the data on J/psi photoproduction on a nucleon is discussed. We evaluate the elastic J/psi +N cross section using a dispersion relation and demonstrate the overall agreement with the predictions from QCD sum rules. Our results are compatible with the phenomenological dissociation cross section evaluated from the experimental data on J/psi production from gamma +A, p +A, and A+A collisions.
