 Searching for new symmetries in the Higgs sector at ATLAS Detector / ATLAS Collaboration ; Fan, Yunyun (Chinese Academy of Sciences (CN)) /ATLAS Collaboration The discovery of the Higgs boson with the mass of 125 GeV confirmed the mass generation mechanism via spontaneous electroweak symmetry breaking and completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many experimental measurements, it is not capable of solely explaining some observations.

 Precision measurements of top-quark couplings and cross sections with the ATLAS detector at the LHC / Mince, Laurynas (University of Glasgow (GB)) /ATLAS Collaboration The Standard Model of particle physics (SM) connects symmetries to the interactions of elementary particles. Effective field theories (EFT) extend the SM with higher-dimension operators that maintain the SM’s symmetries in the low-energy limit. [...] ATL-PHYS-SLIDE-2021-720.- Geneva : CERN, 2021 - 20 p.

 Measurement of the CP violation in Bs0 → J/ψφ decays in p-p collisions at √s = 13 TeV with the ATLAS detector. / Smizanska, Maria (Lancaster University (GB)) /ATLAS Collaboration The Standard Model predicts the CP violating mixing phase, phi_s, to be very small and its SM value is very well constrained, while in many new physics models large phi_s values are expected. Measurements of the time–dependent decay rate of the B_s^0 —> J/psi phi decays provide a theoretically clean method for extracting phi_s. [...] ATL-PHYS-SLIDE-2021-719.- Geneva : CERN, 2021 - 24 p.

 Searches for Dark Matter at Colliders / Behr, Janna Katharina (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration Experiments at particle colliders, such as the LHC, are used to search for Dark Matter (DM) produced in high-energy collisions of Standard Model (SM) particles. A particular strength of collider searches lies in the fact that they not only could be sensitive to DM production but could even shed light on the nature of the SM-DM interaction.

 Measurements of multi-boson production including vector-boson scattering at ATLAS / Liu, Xiaotian (University of Science and Technology of China (CN)) /ATLAS Collaboration Measurements of multiboson production at the LHC probe the electroweak gauge structure of the Standard Model for contributions from anomalous couplings. In this talk we present recent ATLAS results on the measurement of electroweak production of a Zgamma pair in association with two jets, the first observation of three W boson production, as well as the observation of the W pair production in photon-induced collisions.

 Probing the nature of electroweak symmetry breaking with Higgs boson pair-production at ATLAS / Hank, Michael Donald (University of Chicago (US)) /ATLAS Collaboration In the Standard Model, the ground state of the Higgs field is not found at zero but instead corresponds to one of the degenerate solutions minimising the Higgs potential. In turn, this spontaneous electroweak symmetry breaking provides a mechanism for the mass generation of nearly all fundamental particles. [...] ATL-PHYS-SLIDE-2021-715.- Geneva : CERN, 2021 - 28 p.

 The new GeoModel suite, a lightweight detector description and visualization toolkit for HEP / Bianchi, Riccardo Maria (University of Pittsburgh (US)) ; Bandieramonte, Marilena (University of Pittsburgh (US)) ; Boudreau, Joseph (University of Pittsburgh (US)) ; Dell'Acqua, Andrea (CERN) ; Tsulaia, Vakhtang (Lawrence Berkeley National Lab. (US)) /ATLAS Collaboration The GeoModel toolkit is an open-source suite of standalone tools that empowers the user with lightweight tools to describe, visualize, test, and debug detector descriptions and geometries for HEP standalone studies and experiments. GeoModel has been designed with independence and responsiveness in mind and offers a development environment free of other large HEP tools and frameworks, and with a very quick development cycle.

 The ATLAS Data Carousel Project Status and Plans / Klimentov, Alexei (Brookhaven National Laboratory (US)) ; Zhao, Xin (Brookhaven National Laboratory (US)) ; Lassnig, Mario (CERN) /ATLAS Collaboration The High Luminosity upgrade to the LHC, which aims for a ten-fold increase in the luminosity of proton-proton collisions at an energy of 14 TeV, is expected to start operation in 2028/29, and will deliver an unprecedented volume of scientific data at the multi-exabyte scale. This amount of data has to be stored and the corresponding storage system must ensure fast and reliable data delivery for processing by scientific groups distributed all over the world.
