“…In case the v 2 distribution is a 2D Gaussian in the reaction plane, the six-particle cumulant v 2 {6} and higher orders will be equal to v 2 {4} and therefore will add no new information. This has been found to be the case (i.e., v 2 {6} ≈ v 2 {4}) to within 3% for previous data sets [18] and to within less than 2% for the Au + Au data sets used in this analysis. In this approximation for the v 2 fluctuations [17], v 2 {4} is equal to the mean v 2 relative to the reaction plane and v…”

We present STAR measurements of azimuthal anisotropy by means of the two-and four-particle cumulants v 2 (v 2 {2} and v 2 {4}) for Au + Au and Cu + Cu collisions at center-of-mass energies √ s NN = 62.4 and 200 GeV. The difference between v 2 {2} 2 and v 2 {4} 2 is related to v 2 fluctuations (σ v 2 ) and nonflow (δ 2 ). We present an upper limit to σ v 2 /v 2 . Following the assumption that eccentricity fluctuations σ ε dominate v 2 fluctuations σv 2 v 2 ≈ σε ε we deduce the nonflow implied for several models of eccentricity fluctuations that would be required for consistency with v 2 {2} and v 2 {4}. We also present results on the ratio of v 2 to eccentricity.

“…Thus it is difficult to make an accurate estimate of nonflow contributions. The fact that at high p T (p T > 5 GeV/c) the p + p results are very close to central Au + Au [40,43] suggests that the uncertainties are relatively small. In the following we estimate the systematic uncertainties arising from nonflow contributions.…”

We present the results of an elliptic flow, v 2 , analysis of Cu + Cu collisions recorded with the solenoidal tracker detector (STAR) at the BNL Relativistic Heavy Ion Collider at √ s NN = 62.4 and 200 GeV. Elliptic flow as a function of transverse momentum, v 2 (p T ), is reported for different collision centralities for charged hadrons h ± and strangeness-ontaining hadrons K 0 S , , , and φ in the midrapidity region |η| < 1.0. Significant reduction in systematic uncertainty of the measurement due to nonflow effects has been achieved by correlating particles at midrapidity, |η| < 1.0, with those at forward rapidity, 2.5 < |η| < 4.0. We also present azimuthal correlations in p + p collisions at (2010) energy, m T − m, and (ii) at intermediate p T , 2 < p T < 4 GeV/c, it scales with the number of constituent quarks, n q . We have found that ideal hydrodynamic calculations fail to reproduce the centrality dependence of v 2 (p T ) for K 0 S and . Eccentricity scaled v 2 values, v 2 /ε, 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 v 2 /ε depends on the system size, that is, the number of participants N part . This indicates that the ideal hydrodynamic limit is not reached in Cu + Cu collisions, presumably because the assumption of thermalization is not attained.

“…12, v 2 [49] and v 3 obtained with the TPC subevent plane method are compared as a function of transverse momentum with several models for 0%-5%, 20%-30%, and 30%-40% central collisions. The experimental results for the TPC subevent plane method are shown because they eliminate the short-range correlations but yet have a small | η| like the theory calculations.…”

We report measurements of the third harmonic coefficient of the azimuthal anisotropy, v 3 , known as triangular flow. The analysis is for charged particles in Au + Au collisions at √ s NN = 200 GeV, based on data from the STAR experiment at the BNL Relativistic Heavy Ion Collider. Two-particle correlations as a function of their pseudorapidity separation are fit with narrow and wide Gaussians. Measurements of triangular flow are extracted from the wide Gaussian, from two-particle cumulants with a pseudorapidity gap, and also from event plane analysis methods with a large pseudorapidity gap between the particles and the event plane. These results are 014904-2 THIRD HARMONIC FLOW OF CHARGED PARTICLES IN . . . 88, 014904 (2013) reported as a function of transverse momentum and centrality. A large dependence on the pseudorapidity gap is found. Results are compared with other experiments and model calculations. PHYSICAL REVIEW C
