Search for a new scalar decaying into new spin-1 bosons in four-lepton final states with the ATLAS detector / ATLAS Collaboration
A search is conducted for a new scalar boson S, with a mass distinct from that of the Higgs boson, decaying into four leptons (= e, μ) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons Zd: SZdZd4, where the Zd boson has a mass between 15 and 300 GeV, and the S boson has a mass between either 30 and 115 GeV or 130 and 800 GeV.

Search for pair-produced higgsinos decaying via Higgs or Z bosons to final states containing a pair of photons and a pair of b-jets with the ATLAS detector / ATLAS Collaboration
A search is presented for the pair production of higgsinos χ~ in gauge-mediated supersymmetry models, where the lightest neutralinos χ~10 decay into a light gravitino G~ either via a Higgs h or Z boson. The search is performed with the ATLAS detector at the Large Hadron Collider using 139 fb1 of proton-proton collisions at a centre-of-mass energy of s = 13 TeV. [...]

Measurement of t-channel production of single top quarks and antiquarks in pp collisions at 13 TeV using the full ATLAS Run 2 data sample / ATLAS Collaboration
The production of single top quarks and top antiquarks via the t-channel exchange of a virtual W boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC using 140fb1 of ATLAS data. The total cross-sections are determined to be σ(tq)=1378+8pb and σ(t¯q)=845+6pb for top-quark and top-antiquark production, respectively. [...]

Search for high-mass resonances in final states with a τ-lepton and missing transverse momentum with the ATLAS detector / ATLAS Collaboration
A search for high-mass resonances decaying into a tau-lepton and a neutrino using proton–proton collisions at a center-of-mass energy of s=13 TeV is presented. The full Run 2 data sample corresponding to an integrated luminosity of 139 fb1 recorded by the ATLAS experiment in the years 2015-2018 is analyzed. [...]

Measurement of the total and differential cross-sections of tt¯W production in pp collisions at s=13 TeV with the ATLAS detector / ATLAS Collaboration
Measurements of inclusive and differential production cross-sections of a top-quark-top-antiquark pair in association with a W boson (tt¯W) are presented. They are performed by targeting final states with two same-sign or three isolated leptons (electrons or muons) and are based on s=13 TeV proton-proton collision data with an integrated luminosity of 140 fb1, recorded from 2015 to 2018 with the ATLAS detector at the Large Hadron Collider.

Measurement of jet substructure in boosted tt¯ events with the ATLAS detector using 140 fb1 of 13 TeV pp collisions / ATLAS Collaboration
Measurements of the substructure of top-quark jets are presented, using 140 fb1 of 13 TeV pp collision data recorded with the ATLAS detector at the LHC. Top-quark jets reconstructed with the anti-kt algorithm with a radius parameter R=1.0 are selected in top-quark pair (tt¯) events where one top quark decays semileptonically and the other hadronically, or where both top quarks decay hadronically.

Measurement and interpretation of same-sign W boson pair production in association with two jets in pp collisions at s = 13 TeV with the ATLAS detector / ATLAS Collaboration
This paper presents the measurement of fiducial and differential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W±W±jj) using 139 fb1 of proton-proton collision data recorded at a centre-of-mass energy of s=13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity difference. [...]

A precise measurement of the Z-boson double-differential transverse momentum and rapidity distributions in the full phase space of the decay leptons with the ATLAS experiment at s = 8 TeV / ATLAS Collaboration
This paper presents for the first time a precise measurement of the production properties of the Z boson in the full phase space of the decay leptons.
