Search for quantum black hole production in lepton+jet final states using proton--proton collisions at s = 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for quantum black holes in electron+jet and muon+jet invariant mass spectra is performed with 140 fb1 of data collected by the ATLAS detector in proton--proton collisions at s = 13 TeV at the Large Hadron Collider. The observed invariant mass spectrum of lepton+jet pairs is consistent with Standard Model expectations. [...]

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.

Measurement of cross-sections for production of a Z boson in association with a flavor-inclusive or doubly b-tagged large-radius jet in proton-proton collisions at s=13 TeV with the ATLAS experiment / ATLAS Collaboration
We present measurements of cross-sections for production of a leptonically decaying Z boson in association with a large-radius jet in 13 TeV proton-proton collisions at the LHC, using 36 fb1 of data from the ATLAS detector. Integrated and differential cross-sections are measured at particle-level in both a flavor-inclusive and a doubly b-tagged fiducial phase-space. [...]

Measurements of jet observables sensitive to b-quark fragmentation in tˉt events at the LHC with the ATLAS detector / ATLAS Collaboration
Several observables sensitive to the fragmentation of b-quarks into b-hadrons are measured using 36 fb1 of s=13 TeV proton--proton collision data collected with the ATLAS detector at the LHC. Jets containing b-hadrons are obtained from a sample of dileptonic tˉt events, and the associated set of charged-particle tracks is separated into those from the primary pp interaction vertex and those from the displaced b-decay secondary vertex. [...]

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.

Constraints on Higgs boson properties using WW(eνμν)jj production in 36.1fb1 of s=13 TeV pp collisions with the ATLAS detector / ATLAS Collaboration
This article presents the results of two studies of Higgs boson properties using the WW(eνμν)jj final state, based on a dataset corresponding to 36.1 fb1 of s=13 TeV proton-proton collisions recorded by the ATLAS experiment at the Large Hadron Collider. The first study targets Higgs boson production via gluon-gluon fusion and constrains the CP properties of the effective Higgs-gluon interaction. [...]

The ATLAS Inner Detector Trigger performance in pp collisions at 13 TeV during LHC Run 2 / ATLAS Collaboration
The design and performance of the inner detector trigger for the high level trigger of the ATLAS experiment at the Large Hadron Collider during the 2016-18 data taking period is discussed. In 2016, 2017, and 2018 the ATLAS detector recorded 35.6 fb1, 46.9 fb1, and 60.6 fb1 respectively of proton-proton collision data at a centre-of-mass energy of 13 TeV. [...]

Configuration and performance of the ATLAS b-jet triggers in Run 2 / ATLAS Collaboration
Several improvements to the ATLAS triggers used to identify jets containing b-hadrons (b-jets) were implemented for data-taking during Run 2 of the Large Hadron Collider from 2016 to 2018. These changes include reconfiguring the b-jet trigger software to improve primary-vertex finding and allow more stable running in conditions with high pile-up, and the implementation of the functionality needed to run sophisticated taggers used by the offline reconstruction in an online environment.

Search for lepton-flavor-violation in Z-boson decays with τ-leptons with the ATLAS detector / ATLAS Collaboration
A search for lepton-flavor-violating Zeτ and Zμτ decays with pp collision data recorded by the ATLAS detector at the LHC is presented. This analysis uses 139 fb1 of Run 2 pp collisions at s=13 TeV and is combined with the results of a similar ATLAS search in the final state in which the τ-lepton decays hadronically, using the same data set as well as Run 1 data.
