title: "Figure 18c" of "Systematic Study of Azimuthal Anisotropy in Cu$+$Cu and Au$+$Au Collisions at $\sqrt{s_{_{NN}}} = 62.4$ and 200 GeV"

description: The ratio $v_2$/$n_q$ vs. ${KE}_T$/$n_q$ for $\pi$/$K$/$p$ emitted from Au+Au at 62.4 and 200 GeV and Cu+Cu at 200 GeV collisions.
description: BNL-RHIC. We have studied the dependence of azimuthal anisotropy $v_2$ for inclusive and identified charged hadrons in Au+Au and Cu+Cu collisions on collision energy, species, and centrality. The values of $v_2$ as a function of transverse momentum $p_T$ and centrality in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV and 62.4 GeV are the same within uncertainties. However, in Cu+Cu collisions we observe a decrease in $v_2$ values as the collision energy is reduced from 200 to 62.4 GeV. The decrease is larger in the more peripheral collisions. By examining both Au+Au and Cu+Cu collisions we find that $v_2$ depends both on eccentricity and the number of participants, $N_{part}$. We observe that $v_2$ divided by eccentricity (ε) monotonically increases with $N_{part}$ and scales as $N^{1/3}_{part}$. The Cu+Cu data at 62.4 GeV falls below the other scaled $v_2$ data. For identified hadrons, $v_2$ divided by the number of constituent quarks $n_q$ is independent of hadron species as a function of transverse kinetic energy ${KE}_T$ = $m_T$ − $m$ between 0.1 &lt; ${KE}_T$/$n_q$ &lt; 1 GeV. Combining all of the above scaling and normalizations, we observe a near-universal scaling, with the exception of the Cu+Cu data at 62.4 GeV, of $v_2$/($n_q$⋅ε⋅$N^{1/3}_{part}$) vs. ${KE}_T$/$n_q$ for all measured particles.

We present measurements of elliptic and triangular azimuthal anisotropy of charged particles detected at forward rapidity 1 &lt; |$\eta$| &lt; 3 in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV, as a function of centrality. The multiparticle cumulant technique is used to obtain the elliptic flow coefficients $v_2${2}, $v_2${4}, $v_2${6}, and $v_2${8}, and triangular flow coefficients $v_3${2} and $v_3${4}. Using the small-variance limit, we estimate the mean and variance of the event-by-event $v_2$ distribution from $v_2${2} and $v_2${4}. In a complementary analysis, we also use a folding procedure to study the distributions of $v_2$ and $v_3$ directly, extracting both the mean and variance. Implications for initial geometrical fluctuations and their translation into the final state momentum distributions are discussed.
