title: "Figure 15" of "Measurements of $D^{0}$ and $D^{*}$ Production in $p$ + $p$ Collisions at $\sqrt{s}$ = 200 GeV"

description: $c\bar{c}$ production cross section as inferred from D$^0$ and D$^\star$ production in p+p collisions at $\sqrt{s} = 200$ GeV at $|\eta| &lt; 1$ compared with FONLL calculations. The D$^0$ and D$^\star$ data points were divided by the charm quark fragmentation ratios 0.565 ($c \rightarrow$ D$^0$) and 0.224 ($c \rightarrow$ D$^{\star +}$) [34], respectively, to convert to the $c\bar{c}$ production cross section.

description: The STAR Collaboration at the Relativistic Heavy lon Collider presents a systematic study of hightransverse-momentum charged-di-hadron correlations at small azimuthal pair separation $\Delta \phi$ in $d+\mathrm{Au}$ and central $\mathrm{Au}+$ Au collisions at $\sqrt{s_{N N}}=200 \mathrm{GeV}$. Significant correlated yield for pairs with large longitudinal separation $\Delta \eta$ is observed in central $\mathrm{Au}+\mathrm{Au}$ collisions, in contrast to $d+\mathrm{Au}$ collisions. The associated yield distribution in $\Delta \eta \times \Delta \phi$ can be decomposed into a narrow jet-like peak at small angular separation which has a similar shape to that found in $d+$ Au collisions, and a component that is narrow in $\Delta \phi$ and depends only weakly on $\Delta \eta$, the "ridge." Using two systematically independent determinations of the background normalization and shape, finite ridge yield is found to persist for trigger $p_{t}&gt;6 \mathrm{GeV} / c$, indicating that it is correlated with jet production.

(Color online) Perspective views of $2 \mathrm{D}$ charge-independent angular correlations $\Delta \rho / \sqrt{\rho_{\mathrm{ref}}}$ on $\left(\eta_{\Delta}, \phi_{\Delta}\right)$ for Au-Au collisions at $\sqrt{s_{N N}}=200$ and $62 \mathrm{GeV}$ (top and bottom rows, respectively). Centrality increases left to right from most peripheral to most central. Corrected total cross-section fractions are (left to right) $84 \%-93 \%, 55 \%-64 \%, 18 \%-28 \%,$ and $0 \%-5 \%$ for the $200-\mathrm{GeV}$ data and $84 \%-95 \%, 56 \%-65 \%$ $18 \%-28 \%,$ and $0 \%-5 \%$ for the $62 \mathrm{GeV}$ data (see Tables III and IV).
description: We present two-dimensional (2D) two-particle angular correlations on relative pseudorapidity $\eta$ and azimuth $\phi$ for charged particles from Au-Au collisions at $\sqrt{s_{\mathrm{NN}}}=62$ and $200 \mathrm{GeV}$ with transverse momentum $p_{t} \geq 0.15 \mathrm{GeV} / c,|\eta| \leq 1$ and $2 \pi$ azimuth. Observed correlations include $\mathrm{a}$ $\{$ same-side $\}$ (relative azimuth $&lt;\pi / 2$ ) $2 \mathrm{D}$ peak, a closely-related away-side azimuth dipole, and an azimuth quadrupole conventionally associated with elliptic flow. The same-side 2 D peak and away-side dipole are explained by semihard parton scattering and fragmentation (minijets) in proton-proton and peripheral nucleus-nucleus collisions. Those structures follow N-N binary-collision scaling in Au-Au collisions until midcentrality where a transition to a qualitatively different centrality trend occurs within a small centrality interval. Above the transition point the number of same-side and away-side correlated pairs increases rapidly \{relative to $\}$ binary-collision scaling, the $\eta$ width of the same-side $2 \mathrm{D}$ peak also increases rapidly $(\eta$ elongation) and the $\phi$ width actually decreases significantly. Those centrality trends are more remarkable when contrasted with expectations of jet quenching in a dense medium. Observed centrality trends are compared to \{ Isc hijing\} predictions and to the expected trends for semihard parton scattering and fragmentation in a thermalized opaque medium. We are unable to reconcile a semihard parton scattering and fragmentation origin for the observed correlation structure and centrality trends with heavy ion collision scenarios which invoke rapid parton thermalization. On the other hand, if the collision system is effectively opaque to few-GeV partons the observations reported here would be inconsistent with a minijet picture.
