13 Oct 2003 | | Journal: | Nucl.Phys. A742 (2004) 80-94 | | Subject: | nucl-th | | Abstract: | The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow $v_2(eta)$, as determined recently by the PHOBOS experiment for Au+Au collisions at $sqrt{s_{NN}} = 130$ and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of $v_2$ of identified particles at mid-rapidity. The results confirm the indication for quark deconfinement in Au+Au collisions at RHIC, obtained from a successful Buda-Lund hydro model fit to the single particle spectra and two-particle correlation data, as measured by the BRAHMS, PHOBOS, PHENIX and STAR collaborations. | | Source: | arXiv, nucl-th/0310040 | | Services: | Forum | Review | PDF | Favorites | |
