Measurement of double-differential charged-current Drell-Yan cross-sections at high transverse masses in $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS detector / ATLAS Collaboration
This paper presents a first measurement of the cross-section for the charged-current Drell-Yan process $pp\rightarrow W^{\pm} \rightarrow \ell^{\pm} \nu$ above the resonance region, where $\ell$ is an electron or muon. The measurement is performed for transverse masses, $m_{\text{T}}^{\text{W}}$, between 200 GeV and 5000 GeV, using a sample of 140 fb$^{-1}$ of $pp$ collision data at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV collected by the ATLAS detector at the LHC during 2015-2018 [...]

Weakly supervised anomaly detection for resonant new physics in the dijet final state using proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
An anomaly detection search for narrow-width resonances beyond the Standard Model that decay into a pair of jets is presented. The search is based on 139 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=13$ TeV recorded during 2015-2018 with the ATLAS detector at the Large Hadron Collider. [...]

Measurement of $W^{\pm}$-boson differential cross-sections in proton-proton collisions with low pile-up data at $\sqrt{s} = 5.02$ TeV and $13$ TeV with the ATLAS detector / ATLAS Collaboration
High precision single-differential $W^\pm$-boson production cross-sections as a function of electron or muon transverse momentum $p_\mathrm{T}$ or their pseudorapity $\eta$, as well as double-differential cross-sections as functions of these variables, are measured in proton-proton collisions at centre-of-mass energies $\sqrt{s}=5.02$ TeV and 13 TeV. The $W$-boson charge asymmetry as a function of lepton $\eta$ is also measured. [...]

Search for long-lived charged particles using large specific ionisation loss and time of flight in 140 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
This paper presents a search for massive, charged, long-lived particles with the ATLAS detector at the Large Hadron Collider using an integrated luminosity of 140 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=13$ TeV. These particles are expected to move significantly slower than the speed of light. [...]

Measurement of jet track functions in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
Measurements of jet substructure are key to probing the energy frontier at colliders, and many of them use track-based observables which take advantage of the angular precision of tracking detectors. Theoretical calculations of track-based observables require `track functions', which characterize the transverse momentum fraction $r_q$ carried by charged hadrons from a fragmenting quark or gluon.

Configuration, Performance, and Commissioning of the ATLAS $b$-jet Triggers for the 2022 and 2023 LHC data-taking periods / ATLAS Collaboration
In 2022 and 2023, the Large Hadron Collider produced approximately two billion hadronic interactions each second from bunches of protons that collide at a rate of 40 MHz. The ATLAS trigger system is used to reduce this rate to a few kHz for recording. [...]

Search for charged Higgs bosons produced in top-quark decays or in association with top quarks and decaying via $H^{\pm} \to \tau^{\pm}\nu_{\tau}$ in 13 TeV $pp$ collisions with the ATLAS detector / Aad, Georges (Marseille, CPPM) ; Aakvaag, Erlend (Bergen U.) ; Abbott, Braden Keim (Oklahoma U.) ; Abdelhameed, Sara (New York U., Abu Dhabi) ; Abeling, Kira (Gottingen U., II. Phys. Inst.) ; Abicht, Nils Julius (Dortmund U.) ; Abidi, Haider (Brookhaven) ; Aboelela, Mohammed (Southern Methodist U.) ; Aboulhorma, Asmaa (Mohammed V U., Agdal) ; Abramowicz, Halina (Tel Aviv U.) et al.
Charged Higgs bosons produced either in top-quark decays or in association with a top-quark, subsequently decaying via $H^{\pm} \to \tau^{\pm}\nu_{\tau}$, are searched for in 140 $\text{fb}^{-1}$ of proton-proton collision data at $\sqrt{s}=13$ TeV recorded with the ATLAS detector. Depending on whether the top-quark produced together with the $H^{\pm}$ decays hadronically or semi-leptonically, the search targets $\tau$+jets or $\tau$+lepton final states, in both cases with a $\tau$-lepton decaying into a neutrino and hadrons.

Energy scale and resolution for anti-$k_t$ jets with radius parameters $R=0.2$ and 0.6 measured in proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
Jets with different radius parameters $R$ are an important tool to probe quantum chromodynamics processes at different angular scales. Jets with small $R=0.2$ are instrumental in measurements of the substructure of large-$R$ jets resulting from collimated hadronic decays of energetic $W$, $Z$, and Higgs bosons, top quarks, and of potential new resonances.

A measurement is presented of elliptic ($v_2$) and triangular ($v_3$) azimuthal anisotropy coefficients for charged particles produced in Pb+Pb collisions at $\sqrt{s_{_\text{NN}}} = 5.02$ TeV using a data set corresponding to an integrated luminosity of $435$ $\mu b^{-1}$ collected with the ATLAS detector at the LHC in 2018. The values of $v_2$ and $v_3$ are measured for charged particles over a wide range of transverse momentum, $p_\text{T}=$1-400 GeV and in intervals of Pb+Pb collision centrality, 0-60%, using the scalar product and multi-particle cumulant methods.
