(Moore ’05, van Hees ‘05) (Aichelin ’08) (Djordjevic ’06) But even rad+coll cannot Non-Perturbative method is required

25 Elliptic Flow : v 2 Poor statistics, but at least consistent. (Still preliminary, PHENIX : v2~ for pT~3-5GeV)

Conclusions and Outlook 26

27 Heavy quark can be described by relativistic Langevin dynamics with a parameter predicted by AdS/CFT (for R AA ). Prediction for heavy quark correlations  More effort needed for e-h correlations Latest experimental data for v2 seems to have larger elliptic flow  Within our model, coalescence even at high pT is necessary ? Theoretically, heavy quark energy loss at strong coupling should be reconsidered.
