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.

Measurement of differential cross-sections in t¯t and t¯t+jets production in the lepton+jets final state in pp collisions at s = 13 TeV using 140 fb1 of ATLAS data / ATLAS Collaboration
Differential cross-sections for top-quark pair production, inclusively and in association with jets, are measured in pp collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC using an integrated luminosity of 140 fb1. The events are selected with one charged lepton (electron or muon) and at least four jets. [...]

Combination of measurements of the top quark mass from data collected by the ATLAS and CMS experiments at s=7 and 8 TeV / ATLAS Collaboration
A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and 201 of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. [...]

Precise measurements of W- and Z-boson transverse momentum spectra with the ATLAS detector using pp collisions at s=5.02 TeV and 13 TeV / ATLAS Collaboration
This paper describes measurements of the transverse momentum spectra of W and Z bosons produced in proton-proton collisions at centre-of-mass energies of s=5.02 TeV and s=13 TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, Wν and Z (=e or μ), and for W events further separated by charge. [...]

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 ˜χ01 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. [...]

Observation of electroweak production of W+W in association with jets in proton-proton collisions at s = 13 TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the production of W bosons with opposite electric charges in association with two jets is presented based on 140 fb1 of data collected by the ATLAS detector in proton-proton collisions at s=13 TeV. The analysis is sensitive to the scattering of W bosons, which is of particular interest in the ATLAS physics programme as it can be used to probe the electroweak symmetry breaking mechanism of the Standard Model.
