Effect of changes in meson properties in a nuclear medium: J/Y dissociation in nuclear matter, and meson-nucleus bound states

Abstract

We have presented two possible signals for a change of meson properties in a nuclear medium. First, we discussed the impact on the observed J/Ψ suppression in relativistic heavy ion collisions, which has received a lot of interest recently because of the Quark-Gluon Plasma. Second, we discussed the prediction of ω-, η- and η'-nuclear bound states. Both of these signals, for which many experiments are currently being perfomed or planned, certainly will provide important information about the in-medium properties of hadrons.
