    "abstract": "Charmonium production and suppression in In+In and Pb+Pb reactions at SPS\nenergies is investigated with the HSD transport approach within the \u0027hadronic\ncomover model\u0027 as well as the \u0027QGP threshold scenario\u0027. The results of the\ntransport calculations for J/Psi suppression and the Psi prime to J/Psi ratio\nare compared with the recent data of the NA50 and NA60 Collaborations. We find\nthat the comover absorption model - with a single parameter |M_0|^2 for the\nmatrix element squared for charmonium-meson dissociation - performs best with\nrespect to all data sets. The \u0027threshold scenario\u0027 - within different\nassumptions for the melting energy densities - yields a reasonable suppression\nfor J/Psi but fails in reproducing the Psi prime to J/Psi ratio for Pb+Pb at\n158 A GeV. Predictions for Au+Au reactions are presented for a bombarding\nenergy of 25 A GeV in the different scenarios which will allow for a clear\ndistinction between the models from the experimental side at the future FAIR\nfacility.",
