The "Little Bang" in the lab.

• High-energy nucleus-nucleus collisions: fixed-target reactions (√s~17 GeV, SPS) or colliders (√s~200 GeV, RHIC. √s~5.5 TeV, LHC)

  • QGP expected to be formed in a tiny region (~10-14 m) and to last very short times (~10-23 s).
  • Collision dynamics: Diff. observables sensitive to diff. react. stages
