title: "Figure 4 from Auxiliary material" of "Search for heavy neutral leptons in decays of W bosons produced in 13 TeV $pp$ collisions using prompt signatures in the ATLAS detector"

description: Data and estimated background comparison in the two lepton SRs defined for the μ<sup>±</sup>μ<sup>±</sup>e<sup>∓</sup> decay mode. The hatched band represents the total uncertainty of the background. These signal regions are not orthogonal by construction, and data events can be found in more than one signal region.
description: The existence of right-handed neutrinos with Majorana masses below the electroweak scale could help address the origins of neutrino masses, the matter-antimatter asymmetry, and dark matter. In this paper, leptonic decays of $W$ bosons from 140 fb$^{-1}$ of 13 TeV proton-proton collisions at the LHC, reconstructed in the ATLAS experiment, are used to search for heavy neutral leptons produced through their mixing with muon or electron neutrinos in a scenario with lepton number violation. The search is conducted using prompt leptonic decay signatures. The considered final states require two same-charge leptons or three leptons, while vetoing three-lepton same-flavour topologies. No significant excess over the expected Standard Model backgrounds is found, leading to constraints on the heavy neutral lepton's mixing with muon and electron neutrinos for heavy-neutral-lepton masses. The analysis excludes $|U_{e}|^2$ values above $8\times 10^{-5}$ and $|U_{\mu}|^2$ values above $5.0 \times 10^{-5}$ in the full mass range of 8-65 GeV. The strongest constraints are placed on heavy-neutral-lepton masses in the range 15-30 GeV of $|U_{e}|^2 &lt; 1.1 \times 10^{-5}$ and $|U_{\mu}|^2 &lt; 5 \times 10^{-6}$.

description: $v_2${2, $1.1&lt;|\Delta\eta|&lt; 7.8$} of $\mathrm{\pi}^{\pm}$ as a function of $p_{\mathrm{T}}$ in high-multiplicity p--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ 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: "Figure 8 from Auxiliary material" of "Search for heavy neutral leptons in decays of W bosons produced in 13 TeV $pp$ collisions using prompt signatures in the ATLAS detector"

description: Identification of the two lepton signal region chosen to set the limits for the μ<sup>±</sup>μ<sup>±</sup>e<sup>∓</sup> decay mode. The observed (continuous line) and expected (dashed line) exclusion limits at 95&percnt; CL are also shown. The grey boxed area highlights the regions where the fit is not converging for the observed limit, given the low statistics. While they do not yield a result independently, they are further used in a combined fit with the three lepton regions. In these fits, the signal is floated simultaneously in the two lepton and 3ℓ regions, in which case there are enough statistics to converge on a limit. In this high mass region, the two lepton region gives a minor improvement to the limits in the combined fit when compared to the 3ℓ only result.
