2 A. Ster @ ISMD 2003, Cracow  We have strong interaction analogues of familiar phases  Nuclei behave like a liquid  Quark Gluon Plasma –“ Ionize” nucleons with heat –“Compress” them with density  New state of matter Phases of QCD Matter Z. Fodor and S.D. Katz: T c ~ 170 MeV even at finite baryon density. Cross over like transition. (hep-lat/0106007,0104001)

3 A. Ster @ ISMD 2003, Cracow Buda-Lund hydro model  Separation of the Core and the Halo  Core: hydrodynamic evolution  Halo: decay products of long-lived resonances - Analytic expressions for all the observables - 3d expansion, local thermal equilibrium, symmetry - Goes back to known hydro solutions in nonrel limit Principles for Buda-Lund hydro

4 A. Ster @ ISMD 2003, Cracow Buda-Lund hydro model The general form of the emission function: Calculation of observables with core-halo correction: Assuming special shapes for the flux, temperature, chemical potential and flow:

5 A. Ster @ ISMD 2003, Cracow Buda-Lund hydro model Invariant single particle spectrum: Invariant Buda-Lund correlation function: oscillating prefactor! Non-invariant Bertsch-Pratt parameterization: Non-Gaussian BL form -> Gaussian BP approximation:

6 A. Ster @ ISMD 2003, Cracow R out /R side Ratios at 200 GeV <- Buda-Lund prediction Note also: R side /R L -> const (<=1) as m t >> T 0 is another a BL prediction T. Cs. & B. Lorstad, PRC54 (1996) 1390 NPA 590 (1995) 465 reflects symmetry of the flow !

31 A. Ster @ ISMD 2003, Cracow Comparision of expansion rates: RHIC and the Universe Universality of the Hubble expansion u = H r Hubble constant of the Universe: H 0 = 71 ± 7 km/sec/Mpc converted to SI units: H 0 = (2.3 ± 0.2)x10 -12 sec -1 Hubble constant of Au+Au@RHIC-1 Method a)H RHIC = /R G ~ (3.3 ± 0.6)x10 22 sec -1 Method b)H RHIC = 1/  0 ~ (4.9 ± 0.3)x10 22 sec -1 Ratio of expansion rates: H RHIC / H 0 ~ 2 x 10 34 approx. the ratio of the ages of the objects, without correction for inflation...

32 A. Ster @ ISMD 2003, Cracow CONCLUSION The analysis of RHIC Au+Au data from BRAHMS, PHOBOS, PHENIX and STAR show: succesful Buda-Lund hydro fits (also at h+p and Pb+Pb at SPS) indication for deconfinement at RHIC (T > T c = 170 MeV by 3  at RHIC, but not at SPS) evidence for a 3d Hubble flow at RHIC

33 A. Ster @ ISMD 2003, Cracow CONCLUSION Buda-Lund: T 0 > T c at RHIC

34 A. Ster @ ISMD 2003, Cracow NEXT TO DO Fits to : new NA49 data (with Kaon correlation), NA44 data, CERES data at SPS. new run-2 data at RHIC
