title: "Figure 7.0" of "Charged and strange hadron elliptic flow in Cu+Cu collisions at $\sqrt{s_{NN}}$ = 62.4 and 200 GeV"

description: Charged hadron azimuthal anisotropy v2 as a function of pT in 50-60% Cu+Cu collisions at 62.4 GeV. Data tables for 200 GeV are shown in Fig.4.
description: We present the results of an elliptic flow, v2, analysis of Cu+Cu collisions recorded with the solenoidal tracker detector (STAR) at the BNL Relativistic Heavy Ion Collider at $\sqrt{s_{NN}}$ = 62.4 and 200 GeV. Elliptic flow as a function of transverse momentum, v2(pT), is reported for different collision centralities for charged hadrons h± and strangeness-ontaining hadrons K_0^S, Lambda, Xi, and phi in the midrapidity region |eta| &lt; 1.0. Significant reduction in systematic uncertainty of the measurement due to nonflow effects has been achieved by correlating particles at midrapidity, |eta| &lt; 1.0, with those at forward rapidity, 2.5 &lt; |eta| &lt; 4.0. We also present azimuthal correlations in p+p collisions at $\sqrt{s}$ = 200 GeV to help in estimating nonflow effects. To study the system-size dependence of elliptic flow, we present a detailed comparison with previously published results from Au+Au collisions at $\sqrt{s_{NN}}$ = 200GeV. We observe that v2(pT) of strange hadrons has similar scaling properties as were first observed in Au+Au collisions, that is, (i) at low transverse momenta, pT &lt; 2 GeV/c, v2 scales with transverse kinetic energy, mT−m, and (ii) atintermediate pT, 2 &lt; pT &lt; 4 GeV/c, it scales with the number of constituent quarks, nq. We have found that ideal hydrodynamic calculations fail to reproduce the centrality dependence of v2 (pT) for K_0^S and Lambda. Eccentricity scaled v2 values, v2/epsilon, are larger in more central collisions, suggesting stronger collective flow develops in more central collisions. The comparison with Au+Au collisions, which go further in density, shows that v2/epsilon depends on the system size, that is, the number of participants Npart. This indicates that the ideal hydrodynamic limit is not reached in Cu+Cu collisions, presumably because the assumption of thermalization is not attained.
