title: "Figure 8b" of "Measurement of transverse-single-spin asymmetries for midrapidity and forward-rapidity production of hadrons in polarized p+p collisions at $\sqrt{s}=$200 and 62.4 GeV"

description: The $A_N$ of electromagnetic clusters at $\sqrt{s}$ = 200 GeV as a function of $x_F$ for $3.5 &lt; |\eta| &lt; 3.8$.
description: Measurements of transverse-single-spin asymmetries ($A_N$) in $p$+$p$ collisions at $\sqrt{s}$ = 62.4 and 200 GeV with the PHENIX detector at RHIC are presented. At midrapidity, $A_N$ is measured for neutral pion and eta mesons reconstructed from diphoton decay, and, at forward rapidities, neutral pions are measured using both diphotons and electromagnetic clusters. The neutral-pion measurement of $A_N$ at midrapidity is consistent with zero with uncertainties a factor of 20 smaller than previous publications, which will lead to improved constraints on the gluon Sivers function. At higher rapidities, where the valence quark distributions are probed, the data exhibit sizable asymmetries. In comparison with previous measurements in this kinematic region, the new data extend the kinematic coverage in $\sqrt{s}$ and $p_T$ , and it is found that the asymmetries depend only weakly on $\sqrt{s}$. The origin of the forward $A_N$ is presently not understood quantitatively. The extended reach to higher $p_T$ probes the transition between transverse momentum dependent effects at low $p_T$ and multi-parton dynamics at high $p_T$.

title: "Figure 5a" of "Production of omega mesons in p+p, d+Au, Cu+Cu, and Au+Au collisions at sqrt(s_NN)=200 GeV"

description: Invariant transverse momentum spectra of $\omega$ production in $p$+$p$ and $d$+Au collisions at $\sqrt{s}$=200 GeV.
description: The PHENIX experiment at the Relativistic Heavy Ion Collider has measured $\omega$ meson production via leptonic and hadronic decay channels in $p$ + $p$, $d$+Au, Cu+Cu, and Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV.

Measurements in the hadronic decay channel in Cu+Cu and Au+Au collisions show that $\omega$ production has a suppression pattern at high transverse momentum, similar to that of ${\pi}^{0}$ and ${\eta}$ in central collisions, but no suppression is observed in peripheral collisions. The nuclear modification factors, $R_{AA}$, are consistent in Cu+Cu and Au+Au collisions at similar numbers of participant nucleons.
