abstract
At high temperatures, strongly interacting matter becomes a plasma of deconfined quarks and gluons. In statistical QCD, deconfinement and the properties of the resulting quark-gluon plasma can be investigated by studying the in-medium behaviour of heavy quark bound states. In high energy nuclear interactions, quarkonia probe different aspects of the medium formed in the collision. We survey the results of recent charmonium production studies in SPS and RHIC experiments.

Including a phenomenological heavy-light quark potential in the coalescence model enhances the heavy-quark coalescence probability to near unity at low momentum without ad hoc normalization.
Multi-differential constraint analysis of Υ(nS) suppression in high-multiplicity pp and pPb collisions favors an early, globally correlated, topology-sensitive mechanism over local-density or total-multiplicity control.
Remler formalism with in-medium heavy-quark potential describes charmonium yields at SPS energies and supplies estimates for FAIR energies after calibration on p+p and p+A collisions.
Calculations of excitation functions, momentum spectra, and transparency ratios for χ_c1(1P) on 12C and 184W nuclei demonstrate sensitivity to different absorption cross-section scenarios, proposed for extraction via future CEBAF data.
