Charmonium-Hadron Cross Section in a Nonperturbative QCD Approach

Abstract

We calculate the nonperturbative $J/\Psi -N$ and ${\Psi }^{\prime }-N$ cross sections with the model of the stochastic vacuum which has been succesfully applied in many high energy reactions. We also give a quantitative discussion of pre-resonance formation and medium effects.
