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 polarisation of W bosons produced in top-quark decays using dilepton events at s=13 TeV with the ATLAS experiment / ATLAS Collaboration
A measurement of the polarisation of W bosons produced in top-quark decays is presented, using proton-proton collision data at a centre-of-mass energy of s=13 TeV. The data were collected by the ATLAS detector at the Large Hadron Collider and correspond to an integrated luminosity of 139 fb1. [...]

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 tt¯ 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.

Search for new phenomena with top quark pairs in final states with one lepton, jets, and missing transverse momentum in pp collisions at s= 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for new phenomena with top quark pairs in final states with one isolated electron or muon, multiple jets, and large missing transverse momentum is performed. Signal regions are employed to search for two-, three-, and four-body decays of the directly pair-produced supersymmetric partner of the top quark (stop). [...]

Exclusive dimuon production in ultraperipheral Pb+Pb collisions at sNN=5.02 TeV with ATLAS / ATLAS Collaboration
Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei, PbPb(γγ)μμ(Pb()Pb()), is studied using Lint=0.48 nb1 of sNN=5.02 TeV lead-lead collision data at the LHC with the ATLAS detector. Dimuon pairs are measured in the fiducial region pTμ>4 GeV, ημ<2.4, invariant mass mμμ>10 GeV, and pTμμ<2 GeV. [...]

Search for trilepton resonances from chargino and neutralino pair production in s=13 TeV pp collisions with the ATLAS detector / ATLAS Collaboration
A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an R-parity-violating coupling into a lepton and a W,Z, or Higgs boson. The trilepton invariant-mass spectrum is constructed from events with three or more leptons, targeting chargino decays that include an electron or muon and a leptonically decaying Z boson. [...]

Search for dark matter in association with an energetic photon in pp collisions at s = 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for dark matter is conducted in final states containing a photon and missing transverse momentum in proton-proton collisions at s = 13 TeV. The data, collected during 2015-2018 by the ATLAS experiment at the CERN LHC, correspond to an integrated luminosity of 139 fb1. [...]

A search is presented for new phenomena in events characterised by high jet multiplicity, no leptons (electrons or muons), and four or more jets originating from the fragmentation of b-quarks (b-jets). The search uses 139 fb1 of s = 13 TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider during Run 2. [...]
