Charm and beauty production in AA collisions in a Fokker-Planck approach Hendrik van Hees Goethe University Frankfurt and FIAS December 04, 2013 Hendrik van Hees (GU Frankfurt/FIAS) Charm and beauty in AA December 04, 2013 1 / 15 Outline 1 Heavy-quark interactions in the sQGP Heavy quarks in heavy-ion collisions Heavy-quark diffusion: The Langevin Equation 2 Non-perturbative HQ interactions Resonance model for HQ-q Scattering T-matrix approach with lQCD potentials 3 Comparison with data Nonphotonic electrons at RHIC D mesons at LHC Predictions for D mesons at FAIR Dileptons from correlated D D decays 4 Summary and Outlook Hendrik van Hees (GU Frankfurt/FIAS) Charm and beauty in AA December 04, 2013 2 / 15 Motivation Fast equilibration of hot and dense matter in heavy-ion collisions: collective flow (nearly ideal hydrodynamics) sQGP Heavy quarks as calibrated probe of QGP properties produced in early hard collisions: well-defined initial conditions not fully equilibrated due to large masses heavy-quark diffusion probes for QGP-transport properties Langevin simulation within UrQMD-hydro hybrid model sensitivity to medium evolution [P.
