title: "Figure 12d" of "Measurement of neutral mesons in p+p collisions at sqrt(s) = 200 GeV and scaling properties of hadron production"

description: The invariant differential cross section ${d^2 \sigma}$/${2\pi p_T dy p_T}$ of $\omega$ meson production measured in the indicated decay channel. Type A uncertainties are $p_T$ independent. Type C & B systematic uncertainties are residual with Type B having an unknown $p_T$ dependence. For each $y$-coordinate in each $p_T$ bin was varied by the same amount according to the uncertainty Type C.
description: The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the invariant differential cross section for production of $K^0_S$, $\omega$, $\eta^{\prime}$, and $\phi$ mesons in $p$+$p$ collisions at = 200 GeV. Measurements $\omega$ and $\phi$ production in different decay channels give consistent results. New results for the $\phi$ are in agreement with previously published data and extend the measured $p_T$ coverage. The spectral shapes of all hadron transverse momentum distributions measured by PHENIX are well described by a Tsallis distribution functional form with only two parameters, $n$ and $T$, determining the high-$p_T$ and characterizing the low-$p_T$ regions of the spectra, respectively. The values of these parameters are very similar for all analyzed meson spectra, but with a lower parameter $T$ extracted for protons. The integrated invariant cross sections calculated from the fitted distributions are found to be consistent with existing measurements and with statistical model predictions.

title: "Figure 1a" of "Scaling properties of azimuthal anisotropy in Au + Au and Cu + Cu collisions at s(NN)**(1/2) = 200-GeV."

description: $v_2$ vs. $p_T$ for charged hadrons for Au+Au collisions.
description: Detailed differential measurements of the elliptic flow for particles produced in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV are presented. Predictions from perfect fluid hydrodynamics for the scaling of the elliptic flow coefficient $v_2$ with eccentricity, system size and transverse energy are tested and validated. For transverse kinetic energies $KE_T$ ~ $m_T$-$m$ up to ~1 GeV, scaling compatible with the hydrodynamic expansion of a thermalized fluid is observed for all produced particles. For large values of $KE_T$, the mesons and baryons scale separately. A universal scaling for the flow of both mesons and baryons is observed for the full transverse kinetic energy range of the data when quark number scaling is employed. In both cases the scaling is more pronounced in terms of $KE_T$ rather than transverse momentum.
