title: "Ratio of yields for Groomed jet radius $R_g$ for $x_J$&gt;0.4" of "Girth and groomed radius of jets recoiling against isolated photons in lead-lead and proton-proton collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV"

description: Ratio of yields in PbPb to pp for the unfolded groomed jet radius distribution normalized to the number of jets that pass the $x_J$&gt;0.4 selection. Each uncertainty is symmetrized and added in quadrature.All systematic uncertainties have been obtained assuming the PbPb and pp uncertainties are uncorrelated.The negative (-0.05,0) bin accounts for jets that failed the soft-drop grooming condition.
description: This Letter presents the first measurements of the groomed jet radius $R_{\mathrm{g}}$ and the jet girth $g$ in events with an isolated photon recoiling against a jet in lead-lead (PbPb) and proton-proton (pp) collisions at the LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The observables $R_{\mathrm{g}}$ and $g$ provide a quantitative measure of how narrow or broad a jet is. The analysis uses PbPb and pp data samples with integrated luminosities of 1.7~nb$^{-1}$ and 301~pb$^{-1}$, respectively, collected with the CMS experiment in 2018 and 2017. Events are required to have a photon with transverse momentum $p_{\mathrm{T}}^{\gamma} &gt; 100$~GeV and at least one jet back-to-back in azimuth with respect to the photon and with transverse momentum $p_{\mathrm{T}}^{\text{jet}}$ such that $p_{\mathrm{T}}^{\text{jet}}/p_{\mathrm{T}}^{\gamma} &gt; 0.4$. The measured $R_{\mathrm{g}}$ and $g$ distributions are unfolded to the particle level, which facilitates the comparison between the PbPb and pp results and with theoretical predictions. It is found that jets with $p_{\mathrm{T}}^{\text{jet}}/p_{\mathrm{T}}^{\gamma} &gt; 0.8$, i.e, those that closely balance the photon $p_{\mathrm{T}}^{\gamma}$, are narrower in PbPb than in pp collisions. Relaxing the selection to include jets with $p_{\mathrm{T}}^{\text{jet}}/p_{\mathrm{T}}^{\gamma} &gt; 0.4$ reduces the narrowing of the angular structure of jets in PbPb relative to the pp reference. This shows that selection bias effects associated with jet energy loss play an important role in the interpretation of jet substructure measurements.

title: "Table 1" of "Measurement of the Z boson invisible width at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Measured invisible width of the $Z$ boson, $\Gamma(Z\rightarrow \textrm{inv})$.
description: CERN-LHC. A measurement of the invisible width of the $Z$ boson using events with jets and missing transverse momentum is presented using 37 $\mbox{fb\(^{-1}\)}$ of 13 TeV proton--proton data collected by the ATLAS detector in 2015 and 2016. The ratio of $Z\rightarrow \textrm{inv}$ to $Z\rightarrow\ell\ell$ events, where inv refers to non-detected particles and $\ell$ is either an electron or a muon, is measured and corrected for detector effects. Events with at least one energetic central jet with $p_{\textrm{T}} \geq 110$ GeV are selected for both the $Z\rightarrow \textrm{inv}$ and $Z\rightarrow\ell\ell$ final states to obtain a similar phase space in the ratio. The invisible width is measured to be $506\pm2 \textrm{ (stat.)} \pm12 \textrm{ (syst.)}$ MeV and is the single most precise recoil-based measurement. The result is in agreement with the most precise determination from LEP and the Standard Model prediction based on three neutrino generations.

title: "Figure 4(a)" 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: Observed event yields in $\textrm{CR}t\bar{t}\mu$ compared with pre-fit expectations from Monte Carlo simulations, as a function of the scalar sum of lepton and jet transverse momenta, $H_{\mathrm{T}}$. The last bin includes overflow events. `Signal (prod.)' and `Signal (dec.)' refer to the single-top-quark production and top-quark pair decay signal contributions, respectively. The pre-fit signal yield represents all Wilson coefficients set to 0.1 simultaneously for a new physics scale of $\Lambda=1$ TeV.
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.
