Universal scaling of v2 Bessel functions Kinetic energy Spectra eccentricity Effective slope See details below with First predicted for midrapidity: hep-ph/0108067 Predicted for nonzero rapidity: nucl-th/0310040 PHOBOS, nucl-ex/0406021 PHENIX, nucl-ex/0305013 STAR, nucl-ex/0409033 PHOBOS, nucl-ex/0407012 … Transverse expansion rates … Longitudinal expansion … Temperature gradient … Central freeze-out temperature See parameters values for various fits in nucl-th/0605044, nucl-th/0512078 M. Csanád, T. Csörgő, B. Lörstad • Buda-Lund model: based on perfect hydrodynamics (Phys.Rev.C54:1390-1403,1996; Phys.Rev.C67:034904,2003) • Model describes spectra, flow and HBT correlations (J.Phys.G30:S1079-S1082,2004; Nucl.Phys.A742:80-94,2004) • Elliptic flow: measure of hydrodynamic behavior Zero for non-interacting gas, hydro: v2>0 • Buda-Lund result (hep-ph/0108067, nucl-th/0310040, nucl-th/0512078): • Note mechanism for vanishing flow at large rapidities: • Slope parameters: • Transverse energy: • Spectra eccentricity: Spectra and HBT correlations at RHIC, described by the Buda-Lund model
