Hadronic interactions of the J/psi

Abstract

We calculate the cross sections for reactions of the J/psi with light mesons. We also evaluate its finite temperature spectral function. We investigate separately the role of elastic and inelastic channels and we compare their respective importance. We describe J/psi absorption channels that have not been considered previously to our knowledge. The relevance of our study to heavy ion collisions is discussed.
