title: "Table 12" of "Search for the Chiral Magnetic Effect with charge-dependent azimuthal correlations in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}} = 5.44$ TeV"

description: $\langle \cos(\varphi_{\alpha} + \varphi_{\beta} - 2\Psi_{2}) \rangle$ (opposite-same charge pairs) as a function of centrality in Xe-Xe collisions at $\sqrt{s_{\rm NN}} = 5.44$ TeV.
description: Charge-dependent two- and three-particle correlations measured in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}} = 5.44$ TeV are presented. Results are obtained for charged particles in the pseudorapidity range $|\eta|&lt;0.8$ and transverse momentum interval $0.2 \le p_{\rm T} &lt; 5.0$ GeV/$c$ for different collision centralities. The three-particle correlator $\gamma_{\alpha\beta} \equiv \langle \cos(\varphi_\alpha + \varphi_\beta - 2\Psi_2) \rangle$, calculated for different combinations of charge sign $\alpha$ and $\beta$, is expected to be sensitive to the presence of the Chiral Magnetic Effect (CME). Its magnitude is similar to the one observed in Pb-Pb collisions in contrast to a smaller CME signal in Xe-Xe collisions than in Pb-Pb collisions predicted by Monte Carlo (MC) calculations including a magnetic field induced by the spectator protons. These observations point to a large non-CME contribution to the correlator. Furthermore, the charge dependence of $\gamma_{\alpha\beta}$ can be described by a blast wave model calculation that incorporates background effects and by the Anomalous Viscous Fluid Dynamics model with values of the CME signal consistent with zero. The Xe-Xe and Pb-Pb results are combined with the expected CME signal dependence on the system size from the MC calculations including a magnetic field to obtain the fraction of CME contribution in $\gamma_{\alpha\beta}$, $f_{\rm CME}$. The CME fraction is compatible with zero for the most 30% central events in both systems and then becomes positive; averaging over the 0-70% centrality interval yields an upper limit of 2% (3%) and 25% (32%) at 95% (99.7%) confidence level for the CME signal contribution to $\gamma_{\alpha\beta}$ in Xe-Xe and Pb-Pb collisions, respectively.

title: "Table 1" of "Closing in on critical net-baryon fluctuations at LHC energies: cumulants up to third order in Pb$-$Pb collisions"

description: Delta_eta dependence of Kappa_2(pi+-pi-)/, momentum range: 0.6 &lt; p &lt; 1.5 GeV/c.
description: CERN-LHC. Fluctuation measurements are important sources of information on the mechanism of particle production at LHC energies. This article reports the first experimental results on third-order cumulants of the net-proton distributions in Pb--Pb collisions at a center-of-mass energy 5.02 TeV recorded by the ALICE detector. The results on the second-order cumulants of net-proton distributions at 2.76 and 5.02 TeV are also discussed in view of effects due to the global and local baryon number conservation. The results demonstrate the presence of long-range rapidity correlations between protons and antiprotons. Such correlations originate from the early phase of the collision. The experimental results are compared with HIJING and EPOS model calculations, and the dependence of the fluctuation measurements on the phase-space coverage is examined in the context of lattice quantum chromodynamics (LQCD) and hadron resonance gas (HRG) model estimations. The measured third-order cumulants are consistent with zero within experimental uncertainties of about 4% and are described well by LQCD and HRG predictions.

title: "Figure 4 Dzero pp 13 TeV" of "Charm production and fragmentation fractions at midrapidity in pp collisions at $\sqrt{s} = 13$ TeV"

description: $p_{\mathrm{T}}$-differential $\mathrm{D}^{0}$ production cross section at midrapidity ($|y|&lt;0.5$) in pp collisions at $\sqrt{s}$ = 13 TeV

Branching ratio of $\mathrm{D}^{0}\rightarrow\mathrm{K}^-\pi^+$: $(3.95 \pm 0.03)\%$.
Global relative uncertainty on BR: $0.8\%$
Global relative uncertainty on luminosity: $1.6\%$
description: Measurements of the production cross sections of prompt $\mathrm{D}^0$, $\mathrm{D}^+$, $\mathrm{D}^{*+}$, $\mathrm{D}^+_\mathrm{c}$, $\Lambda^+_\mathrm{c}$, and $\Xi^+_\mathrm{c}$ charm hadrons at midrapidity in proton$-$proton collisions at $\sqrt{s}=13$ TeV with the ALICE detector are presented. The D-meson cross sections as a function of transverse momentum ($p_\mathrm{T}$) are provided with improved precision and granularity. The ratios of $p_\mathrm{T}$-differential meson production cross sections based on this publication and on measurements at different rapidity and collision energy provide a constraint on gluon parton distribution functions at low values of Bjorken-$x$ ($10^{-5}-10^{-4}$). The measurements of $\Lambda^+_\mathrm{c}$ ($\Xi^+_\mathrm{c}$) baryon production extend the measured $p_\mathrm{T}$ intervals down to $p_\mathrm{T}=0(3)$~GeV$/c$. These measurements are used to determine the charm-quark fragmentation fractions and the $\mathrm{c}\bar{\mathrm{c}}$ production cross section at midrapidity ($|y|&lt;0.5$) based on the sum of the cross sections of the weakly-decaying ground-state charm hadrons $\mathrm{D}^0$, $\mathrm{D}^+$, $\mathrm{D}^+_\mathrm{c}$, $\Lambda^+_\mathrm{c}$, $\Xi^0_\mathrm{c}$ and, for the first time, $\Xi^+_\mathrm{c}$, and of the strongly-decaying $J/\psi$ mesons. The first measurements of $\Xi^+_\mathrm{c}$ and $\Sigma_\mathrm{c}^{0,+,++}$ fragmentation fractions at midrapidity are also reported. A significantly larger fraction of charm quarks hadronising to baryons is found compared to $\mathrm{e}^+\mathrm{e}^-$ and ep collisions. The $\mathrm{c}\bar{\mathrm{c}}$ production cross section at midrapidity is found to be at the upper bound of state-of-the-art perturbative QCD calculations.
