Spectra, elliptic flow and azimuthally sensitive HBT radii from the Buda-Lund model for root s(NN)=200 GeV Au + Au collisions
(2011) In European Physical Journal A. Hadrons and Nuclei 47(4).- Abstract
- We present calculations of elliptic flow and azimuthal dependence of correlation radii in the ellipsoidally symmetric generalization of the Buda-Lund hydrodynamic model of hadron production in high-energy nuclear collisions. We compare them to data from RHIC by simultaneous fits to azimuthally integrated invariant spectra of pions, kaons and protons-antiprotons measured by PHENIX in Au + Au reactions at center-of-mass energy of 200 AGeV. STAR data were used for azimuthally sensitive two-particle correlation function radii and for the transverse momentum dependence of the elliptic flow parameter v(2). We have found that the transverse flow is faster in the reaction plane than out of plane, which results in a reaction zone that gets slightly... (More)

The model parameters extracted from the fits are shown and discussed. (Less)
