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.
