An indication for deconfinement in Au plus Au collisions at RHIC

In English We present simultaneous, quality fits to final BRAHMS, PHOBOS, STAR and PHENIX data on particle spectra and two-particle Bose-Einstein or HBT correlations as measured in Au+Au collisions at root(S)NN = 130 GeV. Using the Buda-Lund hydro model, the best fit is achieved when the most central 1/8th of the particle emitting volume is superheated to T > T-c = 170 MeV. In contrast, we find no indication for such a hot central region in a similar analysis of Pb+Pb data at CERN SPS.
