Summary (2)

• 1. Energy densities:

• • Maximum dET/dη ~ 600 GeV at midrapidity consistent w/ initial ε > 5 GeV/fm3 > εcrit
  • Seen at SPS ? Yes. ε > 3.9 GeV/fm3 > εcrit (Note, however tcross=1.6 fm/c >t0 = 1 fm/c)

• 2. Elliptic flow:

• • Strong elliptic flow v2 consistent w/ short thermalization times t0 ~ 1 fm/c
  • Seen at SPS ? No. Not as large v2. Described by hydro only with too short freezeout.

• 3. Soft particle spectra:

• • Shapes & yields consistent w/ hydrodynam. (thermal+coll. velocity) source emission
  • Particles ratios consistent w/ chemically equilibrated system before hadronization
  • Seen at SPS ? Yes.

• 4. Hard particle spectra:

• • Strong high pT suppression in central A+A (compared to p+p, p+A & pQCD) consistent w/ final-state partonic energy loss in dense system: dNg/dy~1100
  • Seen at SPS ? Probably. Suppression (not that strong) w.r.t. peripheral.

• 5. Intermediate pT spectra:

• • Enhanced baryon yields & v2 (compared to meson) consistent w/ quark recombination mechanisms in a thermal and dense system
  • Seen at SPS ? No.
