“…This would be a unique probe for the early stage of a partonic phase [72]. Figure 12 shows preliminary STAR [73] and PHENIX [74] measurements of the v 2 for electrons from charm leptonic decays, which have been demonstrated to be closely correlated with charmed meson v 2 [50].…”

We discuss experimental features of identified particle production from nucleus-nucleus collisions. These features reflect hadronization from a deconfined partonic matter whose particle formation scheme is distinctly different from fragmentation phenomenology in elementary collisions. Multi-parton dynamics, such as quark coalescences or recombinations, appear to be essential to explain the experimental measurements at the intermediate transverse momentum of 2--5 GeV/c. Constituent quarks seem to be the dominant degrees of freedom at hadronization. Heavy quark production should help quantify deconfined matter properties.Comment: 18 pages, This report constitutes the combined contribution of the authors to the "VI Quark Confinement and the Hadron Spectrum" conference, held 21--25 September 2004 in Sardinia, Italy covering their oral presentations and the `Deconfinement' discussion session; proceedings to be published by the American Institute of Physic

“…By coupling the limiting temperature idea to a hydrodynamic model calculation, Stöcker et al successfully predicted [34] the energy dependence of the freeze-out temperature. It is worth noting that measurements of the pion phase density [35][36][37] at freeze-out also show saturation at E beam ∼10 A·GeV. At the RHIC energy, the collective velocity parameter seems to be larger than that from collisions at AGS/SPS energies.…”

Systematic trend of the hadron freeze-out conditions from AGS/SPS to RHIC is discussed. The most interesting results from collisions at RHIC are that the system is indeed approaching net-baryon free and the transverse expansion is much stronger than that from collisions at AGS/SPS energies. In order to understand the trend of the collective velocity, an energy scan between $\sqrt{s_{NN}} = 20 - 200 GeV, is important. In addition, systematic studies on the anisotropy parameter $v_2$ and the transverse momentum distributions of $\phi, \Omega,$ and $J / \psi$ are necessary as they will help in determining whether the collectivity is developed at the partonic stage.Comment: Talk presented at the Quark Matter 2001 conference, 8 pages, 8 figures.

“…Also shown on Figure 4 are values from Pb+Pb collisions at 158 AGeV [35] and preliminary data from STAR (Au(130 AGeV)+Au(130 AGeV)) [37], demonstrating the persistence of the universal behavior to RHIC energies. While the phasespace densities achieved at SPS and RHIC are higher than those at AGS at higher p T , presumably due to the greater explosive flow generated, it is remarkable that the "universal" value at low p T is reached already for collisions below maximum AGS energy.…”

The E895 Collaboration at the Brookhaven AGS has performed a systematic investigation of Au+Au collisions at 2-8 AGeV, using a large-acceptance Time Projection Chamber. In addition to extensive measurements of particle flow, spectra, two-particle interferometry, and strangeness production, we have performed novel hybrid analyses, including azimuthally-sensitive pion HBT, extraction of the six-dimensional pion phasespace density, and a first measurement of the Lambda-proton correlation function.Comment: Presented at Quark Matter 2001, 8 pages, 5 figure
