title: "Figure 10c" of "Production of omega mesons in p+p, d+Au, Cu+Cu, and Au+Au collisions at sqrt(s_NN)=200 GeV"

description: $R_{AA}$ of the $\omega$ in Au+Au collisions from the $\omega \rightarrow \pi^0 \gamma$ decay channel.
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. The invariant transverse momentum spectra measured in different decay modes give consistent results. 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.

title: "Figure 3a" of "System-size dependence of open-heavy-flavor production in nucleus-nucleus collisions at $\sqrt{s_{_{NN}}}$=200 GeV"

description: The $p_T$ spectra of electrons from the decays of open heavy flavor hadrons produced in Cu+Cu collisions, separated by centrality.
description: The PHENIX Collaboration at the Relativistic Heavy Ion Collider has measured open heavy flavor production in Cu+Cu collisions at $\sqrt{s_{NN}}$=200 GeV through the measurement of electrons at midrapidity that originate from semileptonic decays of charm and bottom hadrons. In peripheral Cu+Cu collisions an enhanced production of electrons is observed relative to $p$+$p$ collisions scaled by the number of binary collisions. In the transverse momentum range from 1 to 5 GeV/$c$ the nuclear modification factor is $R_{AA}$∼1.4. As the system size increases to more central Cu+Cu collisions, the enhancement gradually disappears and turns into a suppression. For $p_T$ &gt; 3 GeV/$c$, the suppression reaches $R_{AA}$∼0.8 in the most central collisions. The $p_T$ and centrality dependence of $R_{AA}$ in Cu+Cu collisions agree quantitatively with $R_{AA}$ in $d$+Au and Au+Au collisions, if compared at similar number of participating nucleons $\langle N_{part} \rangle$.
