Measurement of the inclusive tˉt production cross section in the lepton+jets channel in pp collisions at s= 7 TeV with the ATLAS detector using support vector machines / ATLAS Collaboration
A measurement of the top quark pair-production cross section in the lepton+jets decay channel is presented. It is based on 4.6 fb1 of s=7 TeV pp collision data collected during 2011 by the ATLAS experiment at the CERN Large Hadron Collider. [...]

Measurement of the top-quark mass using a leptonic invariant mass in pp collisions at s=13 TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the top-quark mass (mt) in the tˉt lepton+jets channel is presented, with an experimental technique which exploits semileptonic decays of b-hadrons produced in the top-quark decay chain. The distribution of the invariant mass mμ of the lepton, (with =e,μ), from the W-boson decay and the muon, μ, originating from the b-hadron decay is reconstructed, and a binned-template profile likelihood fit is performed to extract mt.

Two-particle Bose–Einstein correlations in pp collisions at s=13 TeV measured with the ATLAS detector at the LHC / ATLAS Collaboration
This paper presents studies of Bose-Einstein correlations (BEC) in proton-proton collisions at a centre-of-mass energy of 13 TeV, using data from the ATLAS detector at the CERN Large Hadron Collider. Data were collected in a special low-luminosity configuration with a minimum-bias trigger and a high-multiplicity track trigger, accumulating integrated luminosities of 151 μb1 and 8.4 nb1 respectively. [...]

Measurement of single top-quark production in association with a W boson in the single-lepton channel at s=8TeV with the ATLAS detector / ATLAS Collaboration
The production cross-section of a top quark in association with a W boson is measured using proton-proton collisions at s=8 TeV. The dataset corresponds to an integrated luminosity of 20.2 fb1, and was collected in 2012 by the ATLAS detector at the Large Hadron Collider at CERN. [...]

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking / ATLAS Collaboration
The factor of four increase in the LHC luminosity, from 0.5×1034cm2s1 to 2.0×1034cm2s1, and the corresponding increase in pile-up collisions during the 2015-2018 data-taking period, presented a challenge for ATLAS to trigger on missing transverse momentum. The output data rate at fixed threshold typically increases exponentially with the number of pile-up collisions, so the legacy algorithms from previous LHC data-taking periods had to be tuned and new approaches developed to maintain the high trigger efficiency achieved in earlier operations. [...]

Performance of the upgraded PreProcessor of the ATLAS Level-1 Calorimeter Trigger / ATLAS Collaboration
The PreProcessor of the ATLAS Level-1 Calorimeter Trigger prepares the analogue trigger signals sent from the ATLAS calorimeters by digitising, synchronising and calibrating them to reconstruct transverse energy deposits, which are then used in further processing to identify event features. During the first long shutdown of the LHC from 2013 to 2014, the central components of the PreProcessor, the Multichip Modules, were replaced by upgraded versions that feature modern ADC and FPGA technology in order to ensure optimal performance in the high pile-up environment of LHC Run 2.

Combination of the W boson polarization measurements in top quark decays using ATLAS and CMS data at s= 8 TeV / CMS Collaboration
The combination of measurements of the W boson polarization in top quark decays performed by the ATLAS and CMS Collaborations is presented. The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8 TeV, and corresponding to an integrated luminosity of about 20 fb1 for each experiment.

Performance of the ATLAS muon triggers in Run 2 / ATLAS Collaboration
The performance of the ATLAS muon trigger system is evaluated with protonproton (pp) and heavy-ion (HI) collision data collected in Run 2 during 2015-2018 at the Large Hadron Collider. It is primarily evaluated using events containing a pair of muons from the decay of Z bosons to cover the intermediate momentum range between 25 GeV and 100 GeV. [...]

Search for direct production of electroweakinos in final states with missing transverse momentum and a Higgs boson decaying into photons in pp collisions at s=13 TeV with the ATLAS detector / ATLAS Collaboration
A search for a charginoneutralino pair decaying via the 125 GeV Higgs boson into photons is presented. The study is based on the data collected between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb1 of pp collisions at a centre-of-mass energy of 13 TeV.

Observation of electroweak production of two jets and a Z-boson pair / ATLAS Collaboration
Electroweak symmetry breaking explains the origin of the masses of elementary particles via their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering of massive vector bosons (with spin one) at the Large Hadron Collider allows to probe the nature of electroweak symmetry breaking with an unprecedented sensitivity.
