title: "Table 10" of "Observation of partonic flow in proton-proton and proton-nucleus collisions"

description: $v_2${2, $1.1&lt;|\Delta\eta|&lt; 6.4$} of $\Lambda$ + $\overline \Lambda$ as a function of $p_{\mathrm{T}}$ in high-multiplicity pp collisions at $\sqrt{s_{\mathrm{NN}}} = 13$ TeV.
description: $p_{\mathrm{T}}$-differential $v_2$ measured with the two-particle correlation method for mesons ($\mathrm{\pi}^{\pm}, \mathrm{K}^{\pm}, \mathrm{K_{S}^{0}}$) and baryons ($\mathrm{p}(\bar{\mathrm{p}}), \Lambda(\bar{\Lambda})$) in high-multiplicity p--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV and pp collisions at $\sqrt{s} = 13$ TeV. The multiplicity, $\langle N_{\rm ch} \rangle$, represents the average number of reconstructed, efficiency-corrected charged particles with transverse momentum in the range $0.2 &lt; p_{\rm T} &lt; 3.0$ GeV/$c$, measured at midrapidity ($|\eta| &lt; 0.8$). This work demonstrates the distinctive grouping of anisotropic flow for baryons and mesons in high-multiplicity proton--lead and proton--proton collisions at the Large Hadron Collider (LHC).

title: "Table 1" of "Search for quasi-particle scattering in the quark-gluon plasma with jet splittings in pp and Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV"

description: Groomed relative transverse momentum, $k_{\text{T,g}}$, spectra measured in pp collisions.
$60 &lt; p_{\text{T,ch jet}}^{\text{}} &lt; 80\:\text{GeV}/c$, Dynamical grooming $a = 1.0$

For the "trk eff" and "generator" systematic uncertainty sources, the signed systematic uncertainty breakdowns ($\pm$ vs. $\mp$) denote correlation across bins. For the remaining sources ("unfold"), no correlation information is specified (i.e. $\pm$ is always used). In the publication, the quadrature sum of all sources of systematic uncertainty is reported, neglecting the sign information reported here.
description: The ALICE Collaboration reports measurements of the large relative transverse momentum ($k_{\text{T}}$) component of jet substructure in pp and in central and semicentral Pb$-$Pb collisions at center-of-mass energy per nucleon pair $\sqrt{s_{\text{NN}}}=5.02$ TeV. Enhancement in the yield of such large-$k_{\text{T}}$ emissions in central Pb$-$Pb collisions is predicted to arise from partonic scattering with quasi-particles of the quark--gluon plasma. The analysis utilizes charged-particle jets reconstructed by the anti-$k_{\text{T}}$ algorithm with resolution parameter $R=0.2$ in the transverse-momentum interval $60 &lt; p_{\text{T,ch jet}} &lt; 80$\:$\text{GeV}/c$. The soft drop and dynamical grooming algorithms are used to identify high transverse momentum splittings in the jet shower. Comparison of measurements in Pb$-$Pb and pp collisions shows medium-induced narrowing, corresponding to yield suppression of high-$k_{\text{T}}$ splittings, in contrast to the expectation of yield enhancement due to quasi-particle scattering. The measurements are compared to theoretical model calculations incorporating jet quenching, both with and without quasi-particle scattering effects. These measurements provide new insight into the underlying mechanisms and theoretical modeling of jet quenching.

title: "Table 1" of "Multimuons in cosmic-ray events as seen in ALICE at the LHC"

description: Muon multiplicity distribution measured with the ALICE apparatus and obtained for the whole data sample of Run 2 corresponding to a live time of 62.5 days. The data points are grouped in multiplicity intervals with a width of five units ($N_\mu=5-9,~N_\mu=10-14,~...$), and are located at the center of each interval ($N_\mu=7,~N_\mu=12,~...$). The vertical error bars represent the statistical uncertainties.
description: ALICE is a large experiment at the CERN Large Hadron Collider. Located 52 meters underground, its detectors are suitable to measure muons produced by cosmic-ray interactions in the atmosphere. In this paper, the studies of the cosmic muons registered by ALICE during Run 2 (2015--2018) are described. The analysis is limited to multimuon events defined as events with more than four detected muons ($N_\mu&gt;4$) and in the zenith angle range $0^{\circ}&lt;\theta&lt;50^{\circ}$. The results are compared with Monte Carlo simulations using three of the main hadronic interaction models describing the air shower development in the atmosphere: QGSJET-II-04, EPOS-LHC, and SIBYLL 2.3. The interval of the primary cosmic-ray energy involved in the measured muon multiplicity distribution is about $ 4 \times 10^{15}100$) obtained with QGSJET and SIBYLL is compatible with the data, while EPOS-LHC produces a significantly lower rate ($55\%$ of the measured rate). For both QGSJET and SIBYLL, the rate is close to the data when the composition is assumed to be dominated by heavy elements, an outcome compatible with the average energy $E_\mathrm{prim} \sim 10^{17}$~eV of these events. This result places significant constraints on more exotic production mechanisms.
