ABSTRACT: Heavy quarks (charm and bottom) provide a versatile tool to study properties of the Quark-Gluon Plasma (QGP) and their manifestation in ultrarelativistic heavy-ion collisions. The large quark mass offers unique opportunities for theoretical control over basic in-medium quantities.
Quarkonium bound states are sensitive to Debye screening of the QCD force in medium, as well as to dissociation reactions induced by thermal partons. Recent developments utilizing potential models to evaluate quarkonium spectral functions will be discussed. Uncertainties in using input from lattice-QCD (lQCD) free energies and different approximation schemes will be examined in connection with constraints from lQCD Euclidean correlators. The relations to heavy-quark diffusion will be elaborated and put into context with transport properties of the QGP. The sensitivity of in-medium properties to observables at RHIC for both open and hidden heavy flavor will be sketched.
