title: "Figure 5c" of "Study of central exclusive $\pi^+\pi^-$ production in proton-proton collisions at $\sqrt{s} =$ 5.02 and 13 TeV"

description: Differential cross section as a function of the transverse momentum of the pion pair at 5.02 TeV, compared with generator-level simulations.
description: Central exclusive and semiexclusive production of pi+pi- pairs is measured with the CMS detector in proton-proton collisions at the LHC at center-of-mass energies of 5.02 and 13 TeV. The theoretical description of these nonperturbative processes, which have not yet been measured in detail at the LHC, poses a significant challenge to models. The two pions are measured and identified in the CMS silicon tracker based on specific energy loss, whereas the absence of other particles is ensured by calorimeter information. The total and differential cross sections of exclusive and semiexclusive central pi+pi- production are measured as functions of invariant mass, transverse momentum, and rapidity of the pi+pi- system in the fiducial region defined as transverse momentum pT(pi) &gt; 0.2 GeV and pseudorapidity |eta(pi)| &lt; 2.4. The production cross sections for the four resonant channels f0(500), rho0(770), f0(980), and f2(1270) are extracted using a simple model. These results represent the first measurement of this process at the LHC collision energies of 5.02 and 13 TeV.

title: "Figure 3-3-3" of "Identified particle distributions in p p and Au + Au collisions at s**(1/2) = 200-GeV."

description: Mean transverse momentum of negative particles and (b) $K^-/\pi^-$ and $\bar{p}/\pi^-$ ratios as function of the charged hadron multiplicity. Open symbols are for pp, and filled ones are for Au+Au data. (c) Mid-rapidity $K^-/\pi^-$ ratio as function of $\frac{(dN/dy)_{\pi}}{S}$. Systematic errors are shown for STAR data, and statistical errors for other data.
description: Transverse mass and rapidity distributions for charged pions, charged kaons, protons and antiprotons are reported for sqrt{s_NN}=200 GeV pp and Au+Au collisions at RHIC. The transverse mass distributions are rapidity independent within |y|&lt;0.5, consistent with a boost-invariant system in this rapidity interval. Spectral shapes and relative particle yields are similar in pp and peripheral Au+Au collisions and change smoothly to central Au+Au collisions. No centrality dependence was observed in the kaon and antiproton production rates relative to the pion production rate from medium-central to central collisions. Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and relatively long duration from chemical to kinetic freeze-out in central Au+Au collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.

title: "Figure 1" of "Energy dependence of $\pi^{\pm}$, $p$ and $\bar{p}$ transverse momentum spectrafor Au+Au collisions at $\sqrt{s_{\mathrm {NN}}}$~=~62.4 and 200 GeV"

description: Midrapidity (|y| &lt; 0.5) transverse momentum spectra for pions, protons, anti-protons for various event centrality classes for Au+Au at sqrt(sNN) = 62.4 GeV. Also shown to study the energy dependence are the central 0-12% pion, proton, anti-proton spectra for Au+Au at sqrt(sNN) = 200 GeV.
description: We study the energy dependence of the transverse momentum (pT) spectra for charged pions, protons and anti-protons for Au+Au collisions at \sqrt{s_NN} = 62.4 and 200 GeV. Data are presented at mid-rapidity (|y| &lt; 0.5) for 0.2 &lt; pT &lt; 12 GeV/c. In the intermediate pT region (2 &lt; pT &lt; 6 GeV/c), the nuclear modification factor is higher at 62.4 GeV than at 200 GeV, while at higher pT (pT &gt;7 GeV/c) the modification is similar for both energies. The p/pi+ and pbar/pi- ratios for central collisions at \sqrt{s_NN} = 62.4 GeV peak at pT ~ 2 GeV/c. In the pT range where recombination is expected to dominate, the p/pi+ ratios at 62.4 GeV are larger than at 200 GeV, while the pbar/pi- ratios are smaller. For pT &gt; 2 GeV/c, the pbar/pi- ratios at the two beam energies are independent of pT and centrality indicating that the dependence of the pbar/pi- ratio on pT does not change between 62.4 and 200 GeV. These findings challenge various models incorporating jet quenching and/or constituent quark coalescence.

title: "Figure 1 minimum bias" of "Energy dependence of $\pi^{\pm}$, $p$ and $\bar{p}$ transverse momentum spectrafor Au+Au collisions at $\sqrt{s_{\mathrm {NN}}}$~=~62.4 and 200 GeV"

description: The minimum bias data shown here were extracted from the figures by xyscan. Hence, the dataset is not full (especially in the lower pT range where it is hard to distinguish points), and the statistical errors shown here are an upper limit of the statistical uncertainty based on the marker sizes.

title: "Figure 2 and Figure 10 - part 2" of "Azimuthal di-hadron correlations in d+Au and Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV from STAR"

description: Background-subtracted azimuthal angle difference distributions for associated particles with pT between 1.0 and 2.5 GeV/c and for different ranges of trigger particle pT , ranging from 4.0 − 6.0 GeV/c to 6.0 − 10.0 GeV/c. Results are shown for Au+Au collisions with different centrality and d+Au reference results. The rapidity range is |eta| &lt; 1 and as a result the rapidity-difference |deta| &lt; 2. Results are shown for a restricted acceptance of |deta| &lt; 0.7, using tracks within |eta| &lt; 1. The upper and lower range of the systematic uncertainty due to the v2 modulation of the subtracted background is indicated as well.
description: Yields, correlation shapes, and mean transverse momenta pT of charged particles associated with intermediate to high-pT trigger particles (2.5 &lt; pT &lt; 10 GeV/c) in d+Au and Au+Au collisions at sqrt(sNN) = 200 GeV are presented. For associated particles at higher pT &gt; 2.5 GeV\c, narrow correlation peaks are seen in d+Au and Au+Au, indicating that the main production mechanism is jet fragmentation. At lower associated particle pT &lt; 2 GeV/c, a large enhancement of the near- (dphi ~ 0) and away-side (dphi ~ pi) associated yields is found, together with a strong broadening of the away-side azimuthal distributions in Au+Au collisions compared to d+Au measurements, suggesting that other particle production mechanisms play a role. This is further supported by the observed significant softening of the away-side associated particle yield distribution at dphi ~ pi in central Au+Au collisions.

Open symbols are for pp, and filled ones are for Au+Au data. (c) Mid-rapidity $K^-/\pi^-$ ratio as function of $\frac{(dN/dy)_{\pi}}{S}$.

description: Transverse mass and rapidity distributions for charged pions, charged kaons, protons and antiprotons are reported for sqrt{s_NN}=200 GeV pp and Au+Au collisions at RHIC. The transverse mass distributions are rapidity independent within |y|&lt;0.5, consistent with a boost-invariant system in this rapidity interval. Spectral shapes and relative particle yields are similar in pp and peripheral Au+Au collisions and change smoothly to central Au+Au collisions. No centrality dependence was observed in the kaon and antiproton production rates relative to the pion production rate from medium-central to central collisions. Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and relatively long duration from chemical to kinetic freeze-out in central Au+Au collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.
