Absztrakt:
Buda-Lund hydro-model fits are compared to BRAHMS, PHENIX,
PHOBOS and
STAR data on identified particle spectra, two-particle Bose-
Einstein or
HBT correlations, charged particle pseudorapidity distributions
and
pseudorapidity as well as PT dependent elliptic flow in
rootS(NN) = 130
and 200 GeV Au+Au collisions at RHIC. Preliminary results
indicate that
7/8 of the particle emitting volume is rather cold, with surface
temperature of 105 MeV, but the temperature has a distribution
and the
most central 1/8 of the volume is superheated to temperatures
above the
critical value, T(x) > T-c = 172 3 MeV.
