title: "Figure 5a" of "Search for a heavy composite Majorana neutrino in events with dilepton signatures from proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Exclusion limits on the product of cross section and branching fraction for the electron channel, as a function of the resonance mass hypothesis.
description: Results are presented of a search for a heavy Majorana neutrino $\mathrm{N}_{\ell}$ decaying into two same-flavor leptons $\ell$ (electrons or muons) and a quark-pair jet. A model is considered in which the $\mathrm{N}_{\ell}$ is an excited neutrino in a compositeness scenario. The analysis is performed using a sample of proton-proton collisions at $\sqrt{s}=13\TeV$ recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 138~\fbinv. The data are found to be in agreement with the standard model prediction. For the process in which the $\mathrm{N}_{\ell}$ is produced in association with a lepton, followed by the decay of the $\mathrm{N}_{\ell}$ to a same-flavor lepton and a quark pair, an upper limit at $95\%$ confidence level on the product of the cross section and branching fraction is obtained as a function of the $\mathrm{N}_{\ell}$ mass $m_{\mathrm{N}_{\ell}}$ and the compositeness scale $\Lambda$.For this model the data exclude the existence of $\mathrm{N}_{\mathrm{e}}$ ($\mathrm{N}_{\PGm}$)for $m_{\mathrm{N}_{\ell}}$ below 6.0\,(6.1)\TeV at the limit where $m_{\mathrm{N}_{\ell}}$ is equal to $\Lambda$. For $m_{\mathrm{N}_{\ell}}\approx1\TeV$, values of $\Lambda$ less than 20\,(23)\TeV are excluded.These results represent a considerable improvement in sensitivity, covering a larger parameter space than previous searches in $\Pp\Pp$ collisions at 13\TeV.

title: "Table 1" of "Anisotropic flow and flow fluctuations of identified hadrons in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV"

description: The $p_{T}$-differential $v_2$ measured with two-particle correlations with a pseudorapidity gap of $|\Delta \eta| &gt; 0.8$ for different particle species and centralities in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV.
description: The first measurements of elliptic flow of $\mathrm{\pi}^{\pm}$, $\mathrm{K}^{\pm}$, $\mathrm{p}+\bar{\mathrm{p}}$, $\mathrm{K_{S}^{0}}$, $\Lambda+\bar{\Lambda}$, $\mathrm{\phi}$, $\mathrm{\Xi^{\mp}}$, and $\mathrm{\Omega^{\mp}}$ using multiparticle cumulants in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV are presented. Results obtained with two- ($v_2\{2\}$) and four-particle cumulants ($v_2\{4\}$) are shown as a function of transverse momentum, $p_{\rm T}$, for various collision centrality intervals. Combining the data for both $v_2\{2\}$ and $v_2\{4\}$ also allows us to report the first measurements of the mean elliptic flow, elliptic flow fluctuations, and relative elliptic flow fluctuations for various hadron species. These observables probe the event-by-event eccentricity fluctuations in the initial state and the contributions from the dynamic evolution of the expanding quark--gluon plasma. The characteristic features observed in previous $p_{\rm T}$-differential anisotropic flow measurements for identified hadrons with two-particle correlations, namely the mass ordering at low $p_{\rm T}$ and the approximate scaling with the number of constituent quarks at intermediate $p_{\rm T}$, are similarly present in the four-particle correlations and the combinations of $v_2\{2\}$ and $v_2\{4\}$. In addition, a particle species dependence of flow fluctuations is observed that could indicate a significant contribution from final state hadronic interactions. The comparison between experimental measurements and CoLBT model calculations, which combine the various physics processes of hydrodynamics, quark coalescence, and jet fragmentation, illustrates their importance over a wide $p_{\rm T}$ range.
