Our approach incorporates two sources of $J/\\Psi$ yield: (i) a direct contribution arising from early (hard) parton-parton collisions, subject to subsequent nuclear absorption, quark-gluon plasma and hadronic dissociation, and (ii) statistical production at the hadronization transition by coalescence of $c$ and $\\bar{c}$ quarks. Within an expanding thermal fireball framework, the model reproduces $J/\\Psi$ centrality dependencies observed at the SPS in Pb-Pb and S-U collisions reasonably well.
