title: "Figure 20.2" of "Beam energy dependent two-pion interferometry and the freeze-out eccentricity of pions in heavy ion collisions at STAR"

description: Centrality dependence of the Fourier coefficients that describe azimuthal oscillations of the HBT radii, at mid-rapidity (−0.5 &lt; y &lt; 0.5), in 39 GeV collisions with ⟨$k_T$⟩ ≈ 0.31 GeV/c, from the HHLW method (Gaussian fits to each angular bin) and a single global fit to all angular bins to directly. Error bars include only statistical uncertainties.
description: We present results of analyses of two-pion interferometry in Au+Au collisions at $\sqrt{sNN}$ = 7.7, 11.5, 19.6, 27, 39, 62.4 and 200 GeV measured in the STAR detector as part of the RHIC Beam Energy Scan program. The extracted correlation lengths (HBT radii) are studied as a function of beam energy, azimuthal angle relative to the reaction plane, centrality, and transverse mass ($m_T$) of the particles. The azimuthal analysis allows extraction of the eccentricity of the entire fireball at kinetic freeze-out. The energy dependence of this observable is expected to be sensitive to changes in the equation of state. A new global fit method is studied as an alternate method to directly measure the parameters in the azimuthal analysis. The eccentricity shows a monotonic decrease with beam energy that is qualitatively consistent with the trend from all model predictions and quantitatively consistent with a hadronic transport model.

title: "Figure 12.1" of "High transverse momentum eta meson production in p+p, d+Au and Au+Au collisions at S(NN)**(1/2) = 200-GeV"

description: Inelastic cross section measured in p+p at $\sqrt{s}$=200 GeV through $\eta \rightarrow \gamma \gamma$
description: BNL-RHIC. Inclusive transverse momentum spectra of $\eta$ mesons in the range $p_T\approx$ 2-12 GeV/$c$ have been measured at mid-rapidity (|$\eta$| &lt; 0.35) by the PHENIX experiment at RHIC in p+p, d+Au and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The $\eta$ mesons are reconstructed through their $\eta\rightarrow\gamma\gamma$ channel for the three colliding systems as well as through the $\eta\rightarrow\pi^{0}\pi^{+}\pi^{-}$ decay mode in p+p and d+Au collisions. The nuclear modification factor in d+Au collisions, $R_{dAu}(p_T)\approx$ 1.0-1.1, suggests at most only modest $p_T$ broadening ("Cronin enhancement"). In central Au+Au reactions, the $\eta$ yields are significantly suppressed, with $R_{AuAu}(p_T)\approx$ 0.2. The ratio of $\eta$ to $\pi^{0}$ yields is approximately constant as a function of $p_T$ for the three colliding systems in agreement with the high-$p_T$ world average of $R_{\eta/\pi^{0}}\approx$ 0.5 in hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions for a wide range of center-of-mass energies [$\sqrt{s_{NN}}\approx$ 3-1800 GeV] as well as, for high scaled momentum $x_p$, in $e^{+}e^{-}$ annihilations at $\sqrt{s}$ = 91.2 GeV. These results are consistent with a scenario where high-$p_T$ $\eta$ production in nuclear collisions at RHIC is largely unaffected by initial-state effects, but where light-quark mesons ($\pi^{0}$;$\eta$) are equally suppressed due to final-state interactions of the parent partons in the dense medium produced in Au+Au reactions.
