title: "Figure 4 b" of "Beam-Energy and System-Size Dependence of Dynamical Net Charge Fluctuations"

description: (Color online) Dynamical fluctuations $\nu_{+−,dyn}$, normalized to their value for |$\eta$| &lt; 1, as function of the integrated pseudorapidity range. (a) data for $Au + Au$ collisions at $\sqrt{s_{NN}}$ = 62.4, 200 GeV (0-5%) along with data for $Cu + Cu$ collisions at $\sqrt{s_{NN}}$ = 62.4, 200 GeV (0-10%), are compared to inclusive $p + p$ data at $\sqrt{s}$ = 200 GeV, and (b) data for $Au + Au$ collisions at $\sqrt{s_{NN}}$ = 62.4, 200 GeV (30-40%) along with data for $Cu + Cu$ collisions at $\sqrt{s_{NN}}$ = 62.4, 200 GeV (0-10%), are compared to inclusive $p + p$ collision data at $\sqrt{}s$ = 200 GeV.
description: We present measurements of net charge fluctuations in Au+Au collisions at $\sqrt{s_{NN}}$= 19.6, 62.4, 130, and 200 GeV, Cu+Cu collisions at $\sqrt{s_{NN}}$= 62.4, 200 GeV, and p+p collisions at $\sqrt{s}$= 200 GeV using the dynamical net charge fluctuations measure $\nu_{+−,dyn}$. We observe that the dynamical fluctuations are non-zero at all energies and exhibit a modest dependence on beam energy. A weak system size dependence is also observed. We examine the collision centrality dependence of the net charge fluctuations and find that dynamical net charge fluctuations violate 1/$N_{ch}$ scaling, but display approximate 1/$N_{part}$ scaling. We also study the azimuthal and rapidity dependence of the net charge correlation strength and observe strong dependence on the azimuthal angular range and pseudorapidity widths integrated to measure the correlation.

title: "Table 1" of "Production of $\omega$ mesons in pp collisions at $\sqrt{s}$ = 7 TeV"

description: Invariant differential cross section of OMEGA mesons produced in inelastic pp collisions at center-of-mass energy 7 TeV, the uncertainty of sigma_{MB} of 3.5% is not included in the systematic error.
description: CERN-LHC. The invariant differential cross section of inclusive $\omega(782)$ meson production at midrapidity ($|y|&lt;0.5$) in pp collisions at  $\sqrt{s}=7$ TeV  was measured with the ALICE detector at the LHC over a transverse momentum range of $2 &lt; p_{\text{T}} &lt; 17 \text{GeV}/c$. The $\omega$ meson was reconstructed via its $\omega\rightarrow\pi^+\pi^-\pi^0$ decay channel. The measured $\omega$ production cross section is compared to various calculations: PYTHIA 8.2 Monash 2013 describes the data, while PYTHIA 8.2 Tune 4C overestimates the data by about 50 percent. A recent NLO calculation, which includes a model describing the fragmentation of the whole vector-meson nonet, describes the data within uncertainties below $6$ GeV/c, while it overestimates the data by up to 50 percent for higher $ p_{\text{T}}$.  The $\omega/\pi^0$ ratio is in agreement with previous measurements at lower collision energies and the PYTHIA calculations.  In addition, the measurement is compatible with transverse mass scaling within the measured $p_{\text{T}}$~range and the ratio is constant with $C^{\omega/\pi^{0}}= 0.67  \pm 0.03 \text{(stat)} \pm 0.04 \text{(sys)}$ above a transverse momentum of $2.5$ GeV/$c$.

title: "Table 1" of "Total and differential cross sections of the $dp \to ^3He$ $\eta$ reaction at excess energies between 1 and 15 MeV"

description: Total cross section measurement.
description: COSY Accelerator Jülich. New high precision total and differential cross sections are reported for the reaction d+p -&gt; he3+eta reaction close to threshold. The measurements were performed using the magnetic spectrometer ANKE, which is an internal fixed target facility at the COSY cooler synchrotron. The data were taken for deuteron beam momenta between 3.14641 GeV/c and 3.20416 GeV/c, which corresponds to the range in excess energy Q for this reaction between 1.14 MeV and 15.01 MeV. The normalization was established through the measurement in parallel of deuteron-proton elastic scattering and this was checked through the study of the d+p -&gt; he3+pi_0 reaction. In addition, a smooth variation of the asymmetry parameter (90 degree slope parameter of the differential cross sections) is achieved.

title: "Figure 2, ($Result$ $without$ $dip-angle$ $cut:$)" of "Measurements of $\phi$ meson production in relativistic heavy-ion collisions at RHIC"

description: Background-subtracted invariant mass distributions at 0.4 &lt; $p_{T}$ &lt; 0.8 GeV/c in d + Au 200 GeV collisions (0–100%) with (solid points) and without (open points) the $\delta$-dipangle cut. The dashed curves show a Breit-Wigner (see the text for details) + linear background function fit to the case with the $\delta$-dip-angle cut.
description: BNL-RHIC. We present results for the measurement of $\phi$ meson production via its charged kaon decay channel $\phi$ → $K^{+}K^{-}$ in Au + Au collisions at $\sqrt{s_{NN}} = 62.4, 130,$ and $200 GeV$, and in p + p and d + Au collisions at $\sqrt{s_{NN}} = 200 GeV$ from the STAR experiment at the BNL Relativistic Heavy Ion Collider (RHIC). The midrapidity (|y| &lt; 0.5) $\phi$ meson transverse momentum ($p_{T}$) spectra in central Au + Au collisions are found to be well described by a single exponential distribution. On the other hand, the $p_{T}$ spectra from p + p, d + Au, and peripheral Au + Au collisions show power-law tails at intermediate and high pT and are described better by Levy distributions. The constant $\phi/K^{-}$ yield ratio vs beam species, collision centrality, and colliding energy is in contradiction with expectations from models having kaon coalescence as the dominant mechanism for $\phi$ production at RHIC. The $\Omega/\phi$ yield ratio as a function of $p_{T}$ is consistent with a model based on the recombination of thermal s quarks up to $p_{T}$ ∼ 4 GeV/c, but disagrees at higher transverse momenta. The measured nuclear modification factor, RdAu, for the $\phi$ meson increases above unity at intermediate $p_{T}$ , similar to that for pions and protons, while $R_{AA}$ is suppressed due to the energy loss effect in central Au + Au collisions. Number of constituent quark scaling of both $R_{cp}$ and $v_{2}$ for the $\phi$ meson with respect to other hadrons in Au + Au collisions at $\sqrt{s_{NN}} = 200 GeV$ at intermediate $p_{T}$ is observed. These observations support quark coalescence as being the dominant mechanism of hadronization in the intermediate $p_{T}$ region at RHIC.
