Charmonium-Hadron Cross Section in a Nonperturbative QCD Approach

TL;DR

This paper calculates nonperturbative charmonium-nucleon cross sections using the stochastic vacuum model, providing insights into pre-resonance formation and medium effects in high energy reactions.

Contribution

It introduces a nonperturbative approach to compute charmonium-hadron cross sections, extending the stochastic vacuum model to this context.

Findings

Calculated $J/\Psi$-N and $\Psi'$-N cross sections.

Discussed pre-resonance formation effects.

Analyzed medium effects on charmonium interactions.

Abstract

We calculate the nonperturbative $J/\Psi-N$ and $\Psi'-N$ 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.
