Résumé

New measurements are presented for charged hadron azimuthal correlations at midrapidity in Au+Au collisions at sNN=62.4 and 200 GeV. They are compared to earlier measurements obtained at sNN=130GeV and in Pb+Pb collisions at sNN=17.2GeV. Sizeable anisotropies are observed with centrality and transverse momentum (pT) dependence characteristic of elliptic flow (v2). For a broad range of centralities, the observed magnitudes and trends of the differential anisotropy, v2(pT), change very little over the collision energy range sNN=62-200GeV, indicating saturation of the excitation function for v2 at these energies. Such a saturation may be indicative of the dominance of a very soft equation of state for sNN∼60-200GeV.
