Au+Au Global Results 1: Energy density [PRL 87, 52301 (2001) & QM2002]
ET at mid-rapidity measured by calorimetry: PHENIX EMCal is a good
hadronic calorimeter: EThad = (1.17±0.05) ETEMCal
-
-
<dET/dh> ~ 600 GeV (top 10% central)
70% larger than at SPS energies
Bjorken's estimate of the energy
density (longitudinal expansion):
-
-
-
-
-
-
Energy density (~5 GeV/fm3) @ RHIC > QCD critical density (~1 GeV/fm3)
[ modulo: 1D expansion, not fully baryon-free, thermalization time estimate ]
