Search for new phenomena with top quark pairs in final states with one lepton, jets, and missing transverse momentum in $pp$ collisions at $\sqrt{s}$= 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 $\sqrt{s_{\mathrm{NN}}} = 5.02$ 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, $\mathrm{PbPb} (\gamma\gamma) \rightarrow \mu\mu (\mathrm{Pb}^{(\star)}\mathrm{Pb}^{(\star)} )$, is studied using $\mathcal{L}_{\mathrm{int}} = 0.48$ nb$^{-1}$ of $\sqrt{s_\mathrm{NN}}=5.02$ TeV lead-lead collision data at the LHC with the ATLAS detector. Dimuon pairs are measured in the fiducial region $p_{\mathrm{T}\mu} > 4$ GeV, $\eta_{\mu} < 2.4$, invariant mass $m_{\mu\mu} > 10$ GeV, and $p_{\mathrm{T\mu\mu}} < 2$ GeV. [...]

Search for trilepton resonances from chargino and neutralino pair production in $\sqrt{s} = 13$ 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 $\sqrt{s}$ = 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 $\sqrt{s}$ = 13 TeV. The data, collected during 2015-2018 by the ATLAS experiment at the CERN LHC, correspond to an integrated luminosity of 139 ${fb}^{-1}$. [...]

Search for phenomena beyond the Standard Model in events with large $b$-jet multiplicity using the ATLAS detector at the LHC / ATLAS Collaboration
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 fb$^{-1}$ of $\sqrt{s}$ = 13 TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider during Run 2. [...]

Optimisation of large-radius jet reconstruction for the ATLAS detector in 13 TeV proton–proton collisions / ATLAS Collaboration
Jet substructure has provided new opportunities for searches and measurements at the LHC. Since the first ATLAS studies in Run 1 of the LHC, jet substructure reconstruction has seen continuous development. [...]

Medium-induced modification of $Z$-tagged charged particle yields in Pb+Pb collisions at 5.02 TeV with the ATLAS detector / ATLAS Collaboration
The yield of charged particles opposite to a $Z$ boson with large transverse momentum ($p_{T}$) is measured in 260 ${pb}^{-1}$ of $pp$ and 1.7 ${nb}^{-1}$ of Pb+Pb collision data at 5.02 TeV per nucleon pair recorded with the ATLAS detector at the Large Hadron Collider. The $Z$ boson tag is used to select hard-scattered partons with specific kinematics, and to observe how their showers are modified as they propagate through the quark-gluon plasma created in Pb+Pb collisions.

Search for type-III seesaw heavy leptons in dilepton final states in $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for the pair production of heavy leptons as predicted by the type-III seesaw mechanism is presented. The search uses proton-proton collision data at a centre-of-mass energy of 13 TeV, corresponding to 139 fb$^{-1}$ of integrated luminosity recorded by the ATLAS detector during Run 2 of the Large Hadron Collider.
