Non-perturbative Quarkonium Dissociation in Hadronic Matter
arXiv:hep-ph/9504338 · doi:10.1016/0370-2693(95)00695-H
Abstract
We calculate the dissociation rates of quarkonium ground states by tunnelling and direct thermal activation to the continuum. For hadronic matter at temperatures $T \leq 0.2$ GeV, neither of these mechanisms leads to a sufficiently large dissociation to explain the experimentally observed suppression of charmonium. Dissociation by sequential excitation to excited energy levels, although OZI-forbidden, requires further analysis.
