title: "Table 7" of "Systematic study of flow vector decorrelation in $\mathbf{\sqrt{\textit{s}_{_{\bf NN}}}=5.02}$ TeV Pb-Pb collisions"

description: The factorization ratio $r_{2}$ as a function of $p_{\rm T}^{\rm a}$ with $0.2 &lt; p_{\rm T}^{\rm t} &lt; 0.6$ GeV/$c$ in different centrality intervals
description: Measurements of the $p_\mathrm{T}$-dependent flow vector fluctuations in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV using azimuthal correlations with the ALICE experiment at the LHC are presented. A four-particle correlation approach is used to quantify the effects of flow angle and magnitude fluctuations separately. This paper extends previous studies to additional centrality intervals and provides measurements of the $p_\mathrm{T}$-dependent flow vector fluctuations at $\sqrt{s_\mathrm{NN}} = 5.02$ with two-particle correlations. Significant $p_\mathrm{T}$-dependent fluctuations of the $\vec{V}_{2}$ flow vector in Pb-Pb collisions are found across different centrality ranges, with the largest fluctuations of up to $\sim$15\% being present in the 5\% most central collisions. In parallel, no evidence of significant $p_\mathrm{T}$-dependent fluctuations of $\vec{V}_{3}$ or $\vec{V}_{4}$ is found. Additionally, evidence of flow angle and magnitude fluctuations is observed with more than $5\sigma$ significance in central collisions. These observations in Pb-Pb collisions indicate precisely where the classical picture of hydrodynamic modeling with a common symmetry plane breaks down. This has implications for hard probes at high $p_\mathrm{T}$, which are biased by kinematic-dependent fluctuations of the flow vector direction of at least 23\% in central collisions. Given the presented results, existing theoretical models should be re-examined to improve our understanding of initial conditions, quark--gluon plasma (QGP) properties, and the dynamic evolution of the created system.

title: "Leptonic DV reconstruction efficiency" of "Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"

description: The DV reconstruction efficiency for an HNL with $m_N = 2$ GeV and $c\tau_N = 10$ mm, as a function of the DV radius $r_{DV}$ using the customised vertex reconstruction for a selection of the fully leptonic MC samples. Different flavour combinations are shown.
description: A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a 𝑊 boson along with a muon or electron. Two channels are explored; a leptonic channel, in which the HNL decays into two leptons and a neutrino, and a semi-leptonic channel, in which the HNL decays into a lepton and a charged pion. The search is performed with 140 $fb^{-1}$ of $\sqrt{s}$= 13 TeV proton–proton collision data collected by ATLAS during Run 2 of the Large Hadron Collider. No excess of events is observed; Dirac-like and Majorana-like HNLs with masses below 14.5 GeV and mixing coefficients as small as $10^{−7}$ are excluded at the $95\%$ confidence level. The results are interpreted under different assumptions on the flavour of the leptons from the HNL decays.
