The ATLAS experiment at the CERN Large Hadron Collider: a description of the detector configuration for Run 3 / ATLAS Collaboration
The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of $\mathcal{L}=2\times 10^{34}\mathrm{cm}^{-2}\mathrm{s}^{-1}$ was routinely achieved at the start of fills, twice the design luminosity. [...]

Measurement of the inclusive $t\bar{t}$ production cross section in the lepton+jets channel in $pp$ collisions at $\sqrt{s}$= 7 TeV with the ATLAS detector using support vector machines / ATLAS Collaboration
A measurement of the top quark pair-production cross section in the lepton+jets decay channel is presented. It is based on 4.6 fb$^{-1}$ of $\sqrt{s} = 7$ TeV $pp$ collision data collected during 2011 by the ATLAS experiment at the CERN Large Hadron Collider. [...]

Construction and test of the SM1 type Micromegas chambers for the upgrade of the ATLAS forward muon spectrometer / Agarwala, J (Pavia U.) ; Alviggi, M G (Naples U. ; INFN, Naples) ; Antonelli, M (Frascati) ; Anulli, F (INFN, Rome ; Rome U.) ; Arcangeletti, C (Frascati) ; Auricchio, S (Naples U. ; INFN, Naples) ; Bagnaia, P (INFN, Rome ; Rome U.) ; Bariani, S (Pavia U.) ; Baroncelli, A (Rome III U. ; INFN, Rome3) ; Bashta, I (Rome III U. ; INFN, Rome3) et al.
Large-size Resistive Micromegas have been chosen for the upgrade of the forward muon spectrometer of the ATLAS experiment, the New Small Wheel project. These chambers, together with small-strip Thin Gap Chambers (sTGC), allow reconstruction of high-momentum muon tracks in a high-radiation environment and provide a robust low-threshold single-muon trigger.

Sensitivity projections for a dual-phase argon TPC optimized for light dark matter searches through the ionization channel / Global Argon Dark Matter Collaboration
Dark matter lighter than 10 GeV/c$^2$ encompasses a promising range of candidates. A conceptual design for a new detector, DarkSide-LowMass, is presented, based on the DarkSide-50 detector and progress toward DarkSide-20k, optimized for a low-threshold electron-counting measurement. [...]

Measurement of the top-quark mass using a leptonic invariant mass in $pp$ collisions at $\sqrt{s}=13~\textrm{TeV}$ with the ATLAS detector / ATLAS Collaboration
A measurement of the top-quark mass ($m_t$) in the $t\bar{t}\rightarrow~\textrm{lepton}+\textrm{jets}$ channel is presented, with an experimental technique which exploits semileptonic decays of $b$-hadrons produced in the top-quark decay chain. The distribution of the invariant mass $m_{\ell\mu}$ of the lepton, $\ell$ (with $\ell=e,\mu$), from the $W$-boson decay and the muon, $\mu$, originating from the $b$-hadron decay is reconstructed, and a binned-template profile likelihood fit is performed to extract $m_t$.

Two-particle Bose–Einstein correlations in ${ pp }$ collisions at $\mathbf {\sqrt{s} = 13}$ TeV measured with the ATLAS detector at the LHC / ATLAS Collaboration
This paper presents studies of Bose-Einstein correlations (BEC) in proton-proton collisions at a centre-of-mass energy of 13 TeV, using data from the ATLAS detector at the CERN Large Hadron Collider. Data were collected in a special low-luminosity configuration with a minimum-bias trigger and a high-multiplicity track trigger, accumulating integrated luminosities of 151 $\mu$b$^{-1}$ and 8.4 nb$^{-1}$ respectively.

Separating $^{39}$Ar from $^{40}$Ar by cryogenic distillation with Aria for dark matter searches / DarkSide Collaboration
The Aria project consists of a plant, hosting a 350 m cryogenic isotopic distillation column, the tallest ever built, which is currently in the installation phase in a mine shaft at Carbosulcis S.p.A., Nuraxi-Figus (SU), Italy. Aria is one of the pillars of the argon dark-matter search experimental program, lead by the Global Argon Dark Matter Collaboration. [...]

Sensitivity of future liquid argon dark matter search experiments to core-collapse supernova neutrinos / DarkSide 20k Collaboration
Future liquid-argon DarkSide-20k and ARGO detectors, designed for direct dark matter search, will be sensitive also to core-collapse supernova neutrinos, via coherent elastic neutrino-nucleus scattering. This interaction channel is flavor-insensitive with a high-cross section, enabling for a high-statistics neutrino detection with target masses of $\sim$50~t and $\sim$360~t for DarkSide-20k and ARGO, respectively.

Measurement of single top-quark production in association with a W boson in the single-lepton channel at $\sqrt{s} = 8\,\text {TeV}$ with the ATLAS detector / ATLAS Collaboration
The production cross-section of a top quark in association with a $W$ boson is measured using proton-proton collisions at $\sqrt{s} = 8$ TeV. The dataset corresponds to an integrated luminosity of 20.2 fb$^{-1}$, and was collected in 2012 by the ATLAS detector at the Large Hadron Collider at CERN. [...]

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking / ATLAS Collaboration
The factor of four increase in the LHC luminosity, from $0.5\times 10^{34}\,\textrm{cm}^{-2}\textrm{s}^{-1}$ to $2.0\times 10^{34}\textrm{cm}^{-2}\textrm{s}^{-1}$, and the corresponding increase in pile-up collisions during the 2015-2018 data-taking period, presented a challenge for ATLAS to trigger on missing transverse momentum. The output data rate at fixed threshold typically increases exponentially with the number of pile-up collisions, so the legacy algorithms from previous LHC data-taking periods had to be tuned and new approaches developed to maintain the high trigger efficiency achieved in earlier operations. [...]
