title: "Table 8" of "Search for charged-lepton-flavour violating $\mu\tau qt$ interactions in top-quark production and decay in $pp$ collisions at $\sqrt{s}= 13$ TeV with the ATLAS detector at the LHC"

description: Expected and observed 95$\%$ CL upper limits on the branching ratio ($\mathcal{B}$) corresponding to the decay of a top quark to a muon and a $\tau$ lepton through a cLFV process using specific Wilson coefficients corresponding to 2Q2L EFT operators. Results are shown separately for $\mu\tau ut$ and $\mu\tau ct$ interactions. The lepton generations are denoted by $i,j=2,3$ for $\mu$ and $\tau$ (where $i \neq j$) and the quark generations are denoted by $k=1,2$ for $u$ and $c$, respectively.
description: - CERN-LHC. A search for charged-lepton-flavour violating $\mu\tau qt$ interactions is presented, considering both top-quark production and decay. The data analysed correspond to $140~\textrm{fb}^{-1}$ of proton--proton collisions at a centre-of-mass energy of $\sqrt{s}= 13$ TeV recorded with the ATLAS detector at the Large Hadron Collider. The analysis targets events containing two muons with the same electric charge, a hadronically decaying tau lepton and at least one jet, with exactly one $b$-tagged jet, produced by a $\mu\tau qt$ interaction. Agreement with the Standard Model expectation within $1.6\sigma$ is observed, and limits are set at the $95\%$ CL on the charged-lepton-flavour violation branching ratio of $\mathcal{B}(t \to \mu\tau q) &lt; 8.7 \times 10^{-7}$. An Effective Field Theory interpretation is performed yielding $95\%$ CL limits on Wilson coefficients, dependent on the flavour of the associated light quark and the Lorentz structure of the coupling. These range from $c_{\mathsf{lequ}}^{3(2313)} / \Lambda^{2} &lt; 0.10~\textrm{TeV}^{-2}$ for $\mu\tau ut$ to $c_{\mathsf{ lequ}}^{1(2323)} / \Lambda^{2} &lt; 1.78~\textrm{TeV}^{-2}$ for $\mu\tau ct$. An additional search is performed for single scalar leptoquark production inducing charged lepton flavour violation, with fixed inter-generational couplings. Upper limits on leptoquark coupling strengths are set at the $95\%$ CL, ranging from $\lambda^{\textrm{LQ}} = 1.26$ to $\lambda^{\textrm{LQ}} = 3.68$ for masses between $0.5$ and $2.0$ TeV.

title: "Fit NP ranking" of "Search for charged-lepton-flavour violating $\mu\tau qt$ interactions in top-quark production and decay in $pp$ collisions at $\sqrt{s}= 13$ TeV with the ATLAS detector at the LHC"

description: Ranking of nuisance parameters by post-fit impact on cLFV signal strength $\mu$ (the parameter of interest, POI). The pre-fit (post-fit) impact of each nuisance parameter is calculated as the difference to the fitted value of cLFV signal strength between the nominal fit and a fit when fixing the corresponding nuisance parameter to $\hat{\theta}\pm\Delta\theta$ ($\hat{\theta}\pm\Delta\hat{\theta}$), where $\hat{\theta}$ is the best-fit value of the nuisance parameter and $\Delta\theta$ ($\Delta\hat{\theta}$) is its pre-fit (post-fit) uncertainty. The pulls of the nuisance parameters are calculated relative to zero. These pulls and their post-fit errors, $\Delta\hat{\theta} / \Delta\theta$, are given in the second column of the table.

title: "Table 3" of "Measurements of long-range two-particle correlation over a wide pseudorapidity range in p$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.0$ TeV"

description: $v_{2}\{2\}$ at $p_{\rm T} &gt; 0$ GeV/$c$ as a function of pseudorapidity in different centrality classes using the template fit method
description: In this Letter, measurements of the long-range correlations in p--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$~TeV are extended to a pseudorapidity gap of $\Delta\eta\sim$8 between particles using the ALICE forward multiplicity detectors. After suppressing non-flow correlations, e.g., from jet and resonance decays, the ridge structure is observed to persist up to a very large gap of $\Delta\eta\sim$8 for the first time in p--Pb collisions. This shows that the collective flow-like correlations extend over an extensive pseudorapidity range also in small collision systems such as p--Pb collisions. The pseudorapidity dependence of the second-order anisotropic flow coefficient, \Veta, is extracted from the long-range correlations. The $v(\eta)$ results are presented for a wide pseudorapidity range of $-3.1 &lt;\eta&lt; 4.8$ in various centrality classes in p--Pb collisions. To gain a comprehensive understanding of the source of anisotropic flow in small collision systems, the $v(\eta)$ measurements are compared with hydrodynamic and transport model calculations. The comparison suggests that the final-state interactions play a dominant role in developing the anisotropic flow in small collision systems.

title: "Figure 1a" of "Evidence for the $VH, H\rightarrow \tau\tau$ process with the ATLAS detector in Run 2"

description: Distributions of representative kinematic variables in the misidentified background-enriched same-sign region: (a) the Higgs boson transverse momentum (${p_\text{T}}^H$) in the $WH(\tau_{\mathrm{had}}\tau_{\mathrm{had}})$ category, (b) the missing transverse momentum (${E_{\mathrm{T}}^{\mathrm{miss}}}$) in the $WH(\tau_{\mathrm{lep}}\tau_{\mathrm{had}})$ category, (c) the radial distance (dR$(\ell,\ell)$) between the two light leptons associated to the $Z\to\ell{}\ell$ decay process in the $ZH(\tau_{\mathrm{had}}\tau_{\mathrm{had}})$ category, and (d) the invariant mass ($m_{\ell\ell}$) of the two light leptons associated to the $Z\to\ell{}\ell$ decay in the $ZH(\tau_{\mathrm{lep}}\tau_{\mathrm{had}})$ category. The hatched band represents the pre-fit statistical, experimental and theoretical uncertainties. The signal contributions are considered as part of the predictions and are normalized as predicted by the Standard Model.
description: A measurement of the Standard Model Higgs boson produced inassociation with a $W$ or $Z$ boson and decaying into a pair of$\tau$-leptons is presented.This search is based on proton-proton collision data collected at$\sqrt{s}=13$\, TeV by the ATLAS experiment at the LHC correspondingto an integrated luminosity of 140 fb$^{-1}$. For the Higgs bosoncandidate, only final states with at least one $\tau$-lepton decayinghadronically ($\tau\rightarrow \mathrm{hadrons} + \nu_\tau$) areconsidered. For the vector bosons, only leptonic decay channels areconsidered: $Z \rightarrow \ell\ell$ and $W\rightarrow \ell\nu_\ell$,with $\ell=e,\mu$. An excess of events over the expected background is found with anobserved (expected) significance of 4.2 (3.6) standard deviations,providing evidence of the Higgs boson produced in association with avector boson and decaying into a pair of $\tau$-leptons. The ratio ofthe measured cross-section to the Standard Model prediction is $\mu_{\text{VH}}^{\tau\tau} = 1.28\ ^{+0.30}_{-0.29}\ (\mathrm{stat.})\ ^{+0.25}_{-0.21}\ (\mathrm{syst.})$.
