Illinois at Urbana Champaign (US)) /ATLAS Collaboration
Graph Neural Networks (GNNs) have been shown to produce high accuracy performance on a variety of HEP tasks, including track reconstruction in the TrackML challenge, and tagging in jet physics. However, GNNs are less explored in applications with noisy, heterogeneous or ambiguous data. [...]

Measurements of the CP structure of Higgs-boson couplings with the ATLAS detector / Grefe, Christian (University of Bonn (DE)) /ATLAS Collaboration
Studies of the CP properties of the Higgs boson in various production modes and decay channels are presented. Limits on the mixing of CP-even and CP-odd Higgs states are set by exploiting the properties of diverse final states..

SEARCHES FOR RESONANCES DECAYING TO PAIRS OF HEAVY BOSONS IN ATLAS / Palazzo, Alessandra (INFN Lecce e Universita del Salento (IT)) /ATLAS Collaboration
Many new physics models predict the existence of Higgs-like particles decaying into two bosons (W, Z, photon, or Higgs bosons) making these important signatures in the search for new physics. Searches for Vgamma, VV, and VH resonances have been performed in various final states. [...]

Search for rare and exotic decays of the Higgs boson and additional scalar particles in ATLAS / Boye, Diallo (Brookhaven National Laboratory (US)) /ATLAS Collaboration
The discovery of the Higgs boson with the mass of 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable to solely explain some observations. [...]

Searches for rare top quark production and decay processes with the ATLAS experiment / Miralles Lopez, Marcos (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration
Run 2 of the LHC has witnessed the observation of many rare top quark production processes predicted by the Standard Model and has boosted searches for flavour-changing-neutral-current interactions of the top quark, that are heavily suppressed in the SM. In this contribution highlights of searches by the ATLAS experiment for rare processes involving top quarks are shown. [...]

Measurements of the Higgs boson properties and their interpretations with the ATLAS experiment / Gee, Carolyn (University of California,Santa Cruz (US)) /ATLAS Collaboration
With the full Run 2 pp collision dataset collected at 13 TeV, very detailed measurements of Higgs boson properties and its interactions can be performed using its decays into bosons and fermions, shining light over the electroweak symmetry breaking mechanism. This talk presents the latest measurements of the Higgs boson properties by the ATLAS experiment in various decay channels, including production mode cross sections, simplified template cross sections, as well as their combination and interpretations.

Searches for new phenomena in final states with 3rd generation quarks using the ATLAS detector / Gadow, Philipp (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena, such as heavy vectors or scalar, vector-like quarks, and leptoquarks in final states containing bottom or top quarks. Such final states offer great potential to reduce the Standard Model background, although with significant challenges in reconstructing and identifying the decay products and modelling the remaining background.

Search for electroweak production of supersymmetric sleptons and charginos with the ATLAS detector / Ballabene, Eric (Università degli Studi e INFN Milano (IT)) /ATLAS Collaboration
A new search for the electroweak production of supersymmetric particles decaying into two leptons with missing transverse momentum is presented. Assuming $R$-parity conservation, two simplified models are considered: direct pair production of sleptons decaying into the lightest neutralinos through leptons of the Standard Model (SM) and direct pair production of the lightest charginos decaying into the lightest neutralinos through $W$ bosons of the SM.

ATLAS measurements of photo-nuclear processes in Pb+Pb collisions / Gilbert, Benjamin Jacob (Columbia University (US)) /ATLAS Collaboration
Ultra-peripheral collisions (UPC) of relativistic heavy-ion beams lead to a diverse set of photon-nucleus interactions. This talk presents two recent ATLAS measurements of photo-nuclear processes in Pb+Pb collisions at 5.02 TeV. [...]

Recent searches for new phenomena with the ATLAS detector / Fawcett, William James (University of Cambridge (GB)) /ATLAS Collaboration
Many theories beyond the Standard Model (BSM) have been proposed to address several of the Standard Model shortcomings, such as the origin of dark matter and neutrino masses, the fine-tuning of the Higgs Boson mass, or the observed pattern of masses and mixing angles in the quark and lepton sectors. Many of these BSM extensions predict new particles or interactions directly accessible at the LHC. [...]
