A search for dark matter produced in association with a dark Higgs boson decaying into a Higgs boson pair in 3$b$ or 4$b$ final states using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
A search is performed for dark matter particles produced in association with a resonant pair of Higgs bosons using 140 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. [...]

Search for squarks and gluinos in $pp$ collisions at $\sqrt{s} = 13$ TeV and $13.6$ TeV in events with $\tau$-leptons, jets and missing transverse momentum using the ATLAS detector
A search for R-parity-conserving supersymmetry in events with large missing transverse momentum, jets and at least one hadronically decaying $\tau$-lepton is presented. [...]

Jet radius dependence of dijet momentum balance and suppression in Pb+Pb collisions at 5.02 TeV with the ATLAS detector / Romero, Anabel (Univ. Illinois at Urbana Champaign (US)) /ATLAS Collaboration
Measurements of jets that traverse the QGP provide insights into the jet energy loss. Considering jets of various radii can help elucidate how the parton energy is transferred to the medium as well as the medium response. [...]

Missing Transverse Momentum Performance at ATLAS / Rutherford Colmenares, Sebastian (University of Cambridge (GB)) ; Pacey, Holly (University of Oxford (GB)) /ATLAS Collaboration
This poster presents the reconstruction of missing transverse momentum ($\mathrm{p}_{\mathrm{T}}^{\mathrm{miss}}$) in proton-proton collisions, in Run-2 data-taking at the ATLAS experiment. This is a challenging task involving many detector inputs, combining fully calibrated electrons, muons, photons, hadronically decaying $\tau$-leptons, hadronic jets, and soft activity from remaining tracks.

Determination of the strong-coupling constant from the Z-boson transverse-momentum distribution / Schmieden, Kristof (Johannes Gutenberg Universitaet Mainz (DE)) /ATLAS Collaboration
The coupling constant of the strong force is determined from the transverse-momentum distribution of Z bosons produced in 8 TeV proton-proton collisions. The Z-boson cross sections are measured in the full phase space of the decay leptons. [...]

Calibration of a soft secondary vertex tagger using proton-proton collisions at $\sqrt{s}=$13 TeV with the ATLAS detector / ATLAS Collaboration
Several processes studied by the ATLAS experiment at the Large Hadron Collider produce low-momentum $b$-flavored hadrons in the final state. This paper describes the calibration of a dedicated tagging algorithm that identifies $b$-flavored hadrons outside of hadronic jets by reconstructing the soft secondary vertices originating from their decays.
