    "abstract": "The effect of color screening on the formation of a heavy quark-antiquark\n($Q\\bar{Q}$) bound state--such as the $J/\\psi$ meson--is studied using a\nconstituent-quark model. The response of the nuclear medium to the addition of\ntwo color charges is simulated directly in terms of its quark constituents via\na string-flip potential that allows for quark confinement within hadrons yet\nenables the hadrons to separate without generating unphysical long-range\nforces. Medium modifications to the properties of the heavy meson, such as its\nenergy and its mean-square radius, are extracted by solving Schr\\\"odinger\u0027s\nequation for the $Q\\bar{Q}$ pair in the presence of a (screened)\ndensity-dependent potential. The density dependence of the heavy-quark\npotential is in qualitative agreement with earlier studies of its temperature\ndependence extracted from lattice calculations at finite temperature. In the\npresent model it is confirmed that abrupt changes in the properties of the\n$J/\\psi$-meson in the hadronic medium ({\\it plasma}), correlate strongly with\nthe deconfining phase transition.",
