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
An anomaly detection search for narrow-width resonances beyond the Standard Model that decay into a pair of jets is presented. [...]

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. [...]

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. [...]

Searches in the long-lived particle and dark sectors / Trocino, Daniele (INFN, Turin) /ATLAS and CMS Collaborations
Searches for dark matter (DM) and long-lived particles (LLPs) are a key focus of the ATLAS and CMS experiments at the Large Hadron Collider. Astrophysical evidence points to the existence of DM, but its nature remains elusive. [...]

Estimation of backgrounds from jets misidentified as $\tau$-leptons using the Universal Fake Factor method with the ATLAS detector / ATLAS Collaboration
Processes with $\tau$-leptons in the final state are important for Standard Model measurements and searches for physics beyond the Standard Model. [...]

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. [...]

Searches for top associated DM production at the LHC / Stafford, Dominic William (DESY) /ATLAS and CMS Collaborations
Recent searches for dark matter (DM) produced in association with top quarks from the ATLAS and CMS experiments using data collected between 2015 and 2018 are presented. These comprise searches from both experiments for DM in association with a single top quark; an improved ATLAS search for DM in single lepton $t\bar{t}$ final states; an ATLAS search stop squarks decaying to a top quark, a charm quark and neutralinos; and a CMS search for DM produced in association with a pair of top quarks or a single top.
