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 SS, with a mass distinct from that of the Higgs boson, decaying into four leptons (== ee, μμ) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons ZdZd: SZdZd4SZdZd4, where the ZdZd boson has a mass between 15 and 300 GeV, and the SS boson has a mass between either 30 and 115 GeV or 130 and 800 GeV.

Precise measurements of WW- and ZZ-boson transverse momentum spectra with the ATLAS detector using pppp collisions at s=5.02s=5.02 TeV and 1313 TeV / ATLAS Collaboration
This paper describes measurements of the transverse momentum spectra of WW and ZZ bosons produced in proton-proton collisions at centre-of-mass energies of s=5.02s=5.02 TeV and s=13s=13 TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, WνWν and ZZ (=e=e or μμ), and for WW events further separated by charge. [...]

Search for pair-produced higgsinos decaying via Higgs or ZZ bosons to final states containing a pair of photons and a pair of bb-jets with the ATLAS detector / ATLAS Collaboration
A search is presented for the pair production of higgsinos ˜χ~χ in gauge-mediated supersymmetry models, where the lightest neutralinos ˜χ01~χ01 decay into a light gravitino ˜G~G either via a Higgs hh or ZZ boson. The search is performed with the ATLAS detector at the Large Hadron Collider using 139 fb11 of proton-proton collisions at a centre-of-mass energy of ss = 13 TeV. [...]

Observation of electroweak production of W++W in association with jets in proton-proton collisions at ss = 13 TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the production of WW bosons with opposite electric charges in association with two jets is presented based on 140 fb11 of data collected by the ATLAS detector in proton-proton collisions at s=13s=13 TeV. The analysis is sensitive to the scattering of WW 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.

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 tt-channel exchange of a virtual WW boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC using 140fb1140fb1 of ATLAS data. The total cross-sections are determined to be σ(tq)=137+88pbσ(tq)=137+88pb and σ(ˉtq)=84+65pbσ(¯tq)=84+65pb for top-quark and top-antiquark production, respectively. [...]

Search for new particles in final states with a boosted top quark and missing transverse momentum in proton-proton collisions at ss = 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for events with one top quark and missing transverse momentum in the final state is presented. The fully hadronic decay of the top quark is explored by selecting events with a reconstructed boosted top-quark topology produced in association with large missing transverse momentum. [...]

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=13s=13 TeV is presented. The full Run 2 data sample corresponding to an integrated luminosity of 139 fb11 recorded by the ATLAS experiment in the years 2015-2018 is analyzed. [...]

This paper presents a search for top-squark pair production in final states with a top quark, a charm quark and missing transverse momentum. The data were collected with the ATLAS detector during LHC Run 2 and corresponds to an integrated luminosity of 139fb11 of proton-proton collisions at a centre-of-mass energy of ss = 13 TeV. [...]

A statistical combination of ATLAS Run 2 searches for charginos and neutralinos at the LHC / ATLAS Collaboration
Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using 139139fb11 of pppp collision data at s=13s=13TeV with the ATLAS detector at the Large Hadron Collider. Searches targeting pure-wino chargino pair production, pure-wino chargino-neutralino production, or higgsino production decaying via Standard Model WW, ZZ, or hh bosons are combined to extend the mass reach to the produced SUSY particles by 30-100 GeV.

Interpretations of the ATLAS measurements of Higgs boson production and decay rates and differential cross-sections in pppp collisions at s=13s=13 TeV / ATLAS Collaboration
Measurements of the Higgs boson production times decay rates and differential cross-sections have recently been performed by the ATLAS experiment in several decay channels using up to 139 fb11 of proton-proton collision data at s=13s=13 TeV recorded at the Large Hadron Collider. This paper presents multiple interpretations of these Higgs boson measurements. [...]
