Heavy quarkonia in heavy-ion collisions

Starting from a historical perspective on both, theoretical and experimental developments, the basic concepts for describing the phenomena summarized as "anomalous quarkonia suppression" are developed. The theoretical approach is built on information for the in-medium modification of hadronic properties obtained from Lattice QCD studies, as well as from effective models. We emphasize the powerful techniques of thermodynamic Green functions (T-matrices) in order to derive the necessary input quantities for a description of heavy quarkonia suppression and regeneration within a kinetic theory. The perspectives from future experiments on charmonium and bottomonium production for our understanding of hadronic matter under extreme conditions are discussed.
