title: "Table 103" of "Multiplicity dependence of light-flavor hadron production in pp collisions at $\sqrt{s}$ = 7 TeV"

description: $n$ from blast-wave fit to pPb collisions at $\sqrt{s}$ = 5.02 TeV
description: Comprehensive results on the production of unidentified charged particles, $\pi^{\pm}$, K$^{\pm}$, K$^{0}_{\text{s}}$, K*(892)$^{0}$, p, $\bar{\text{p}}$, $\phi$(1020), $\Lambda$, $\bar{\Lambda}$, $\Xi^{-}$, $\bar{\Xi}^{+}$, $\Omega^{-}$ and $\bar{\Omega}^{+}$ hadrons in proton-proton (pp) collisions at $\sqrt{s}$ = 7 TeV at midrapidity ($|y| &lt; 0.5$) as a function of charged-particle multiplicity density are presented. In order to avoid auto-correlation biases, the actual transverse momentum ($p_{\text{T}}$) spectra of the particles under study and the event activity are measured in different rapidity windows. In the highest multiplicity class, the charged-particle density reaches about 3.5 times the value measured in inelastic collisions. While the yield of protons normalized to pions remains approximately constant as a function of multiplicity, the corresponding ratios of strange hadrons to pions show a significant enhancement that increases with increasing strangeness content. Furthermore, all identified particle to pion ratios are shown to depend solely on charged-particle multiplicity density, regardless of system type and collision energy. The evolution of the spectral shapes with multiplicity and hadron mass shows patterns that are similar to those observed in p-Pb and Pb--Pb collisions at LHC energies. The obtained \pt\ distributions and yields are compared to expectations from QCD-based pp event generators as well as to predictions from thermal and hydrodynamic models. These comparisons indicate that traces of a collective, equilibrated system are already present in high-multiplicity pp collisions.

title: "Table 1" of "Anisotropic flow in Xe-Xe collisions at $\mathbf{\sqrt{s_{\rm{NN}}} = 5.44}$ TeV"

description: No table description available.
description: The first measurements of anisotropic flow coefficients vn for mid-rapidity charged particles in Xe--Xe 5.44 TeV are presented. Comparing these measurements to those from Pb-Pb 2.76 TeV, v2 is found to be suppressed for mid-central collisions at the same centrality, and enhanced for central collisions. The values of v3 are generally larger in Xe--Xe than in Pb--Pb at a given centrality. These observations are consistent with expectations from hydrodynamic predictions. When both v2 and v3 are divided by their corresponding eccentricities for a variety of initial state models, they generally scale with transverse density when comparing Xe--Xe and Pb--Pb, with some deviations observed in central Xe--Xe and Pb--Pb collisions. These results assist in placing strong constraints on both the initial state geometry and medium response for relativistic heavy-ion collisions.

title: "Table 1" of "Suppression of $\Lambda(1520)$ resonance production in central Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV"

description: $p_{\rm T}$-differential yields of $\Lambda$(1520) (sum of particle and anti-particle states) at midrapidity in the 0-20% centrality class. The uncertainty 'syst,uncorrelated' indicates the systematic uncertainty after removing the contributions common to all centrality classes
description: CERN-LHC. The production yield of the $\Lambda$(1520) baryon resonance is measured at mid-rapidity in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV with the ALICE detector at the LHC. The measurement is performed in the $\Lambda$(1520) $\to$ p K$^{-}$ (and charge conjugate) hadronic decay channel as a function of the transverse momentum ($p_{\rm T}$) and collision centrality. The $p_{\rm T}$-integrated production rate of $\Lambda$(1520) relative to $\Lambda$ in central collisions is suppressed by about a factor of 2 with respect to peripheral collisions. This is the first observation of the suppression of a baryonic resonance at LHC and the first evidence of $\Lambda$(1520) suppression in heavy-ion collisions. The measured $\Lambda$(1520)/$\Lambda$ ratio in central collisions is smaller than the value predicted by the statistical hadronisation model calculations. The shape of the measured $p_{\rm T}$ distribution and the centrality dependence of the suppression are reproduced by the EPOS3 Monte Carlo event generator. The measurement adds further support to the formation of a dense hadronic phase in the final stages of the evolution of the fireball created in heavy-ion collisions, lasting long enough to cause a significant reduction in the observable yield of short-lived resonances.

description: Reconstructed mass of $\rho^{0}$ meson in pp collisions at $\sqrt{s}=2.76~{\rm TeV}$.
description: The production of $\rho^{0}$ mesons is measured with the ALICE detector in pp and Pb-Pb collisions at the centre-of-mass energy per nucleon pair, $\sqrt{s_{\rm NN}}$ = 2.76 TeV. The yields of $\rho^{0}$ for rapidity $|y|&lt;0.5$ are presented as a function of transverse momentum ($p_{\rm T}$). The $p_{\rm T}$-integrated and $p_{\rm T}$-differential particle ratios $\rho^{0}/\pi$ are obtained in pp and Pb--Pb collisions. The nuclear modification factors $R_{\rm AA}$ are computed using a proton-proton reference at $\sqrt{s} = 2.76$ TeV.
