  5. QCD phase diagram QGP(200 Mev~10^12 K)

  6. Relativistic Heavy Ion Collision 1. Gold-Gold collision. 2. Center of mass energy: 200 Gev.

  7. Thermalization time Boost invariant parameter

  8. Hydrodynamics Hydrodynamic equations (Ideal fluid) Energy-momentum tensor Dissipative part Shear viscosity

  9. Properties 1. Thermalization time . 2. Elliptic flow. 3. Shear viscosity. 4. Jet quenching parameter. 5. QuarkoniaSuppression. 6. Chiral magnetic effect.

  10. Elliptic flow Elliptic flow Symmteries:

  11. Shear viscosity

  12. ? • Jet quenching Jet quenching refers to a suite of experimental observables that together reveal what happens when a very energetic quark or gluon (with momentum much greater than the temperature) plows through the strongly coupled plasma.

  13. Nuclear modification factor

  14. QuarkoniaSuppression Quarkonia: Mesons made of a heavy quark-antiquark pair. They are significantly smaller than typical mesons or baryons.

  15. (2S+3S) Suppression
