Transforming Jet Flavor Tagging at ATLAS / Lin, Storm (Stony Brook University (US)) /ATLAS Collaboration
The identification of jets containing b-hadrons is essential for many physics analyses at the LHC, including precision measurements of Higgs boson and top-quark processes, as well as searches for physics beyond the Standard Model. We present recent improvements in the discrimination of b-jets from jets originating from lighter quarks using the ATLAS detector. [...]

Results from muon object performance with the ATLAS experiment at the LHC using Run-3 proton-proton collision data / Austrup, Volker Andreas (The University of Manchester (GB)) /ATLAS Collaboration
The reconstruction and precise measurement of muons are essential for a wide range of physics analyses within the ATLAS experiment at the Large Hadron Collider (LHC). During Run-3, the ATLAS Muon Spectrometer underwent major upgrades, most notably the installation of the New Small Wheel system, designed to improve tracking and triggering performance in the forward region.

Overview of EFT-based searches involving top quarks at ATLAS / Eckerova, Barbora (Comenius University (SK)) /ATLAS Collaboration
Many-parameter fits to precise measurements in the framework of the Standard Model Effective Field Theory are becoming a standard interpretation of LHC and other collider data. In this contribution an overview is given of state-of-the-art EFT interpretations in ATLAS with particular emphasis on results in the top quark sector..

Jet energy scale and resolution calibration from hadronically decaying $W$ boson in $t\bar{t}$ events in ATLAS / Dohnalova, Adriana (Comenius University (SK)) /ATLAS Collaboration
Jet energy scale (JES) and jet energy resolution (JER) uncertainties are among the dominant systematic uncertainties in many ATLAS measurements. After the application of simulation-based calibrations, residual differences between data and simulation are corrected using data-driven in situ techniques. [...]

The upgrade of the ATLAS Trigger and Data Acquisition system for the High Luminosity LHC / Todome, Kazuki (Institute of Science Tokyo (JP)) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS experiment at CERN is constructing upgraded system for the "High Luminosity LHC", with collisions due to start in 2030. In order to deliver an order of magnitude more data than previous LHC runs, 14 TeV protons will collide with an instantaneous luminosity of up to 7.5 x 10e34 cm^-2s^-1, resulting in much higher pileup and data rates than the current experiment was designed to handle.

Results on photon-photon scattering processes in ultra-peripheral Pb+Pb collisions with ATLAS / Beresford, Lydia Audrey (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
In ultra-relativistic heavy-ion collisions, large rates of $\gamma\gamma$ processes arise from the intense electromagnetic fields generated by the colliding nuclei. These $\gamma\gamma$ interactions provide a powerful laboratory to study reactions that may be sensitive to physics beyond the Standard Model In ultra-peripheral collisions (UPCs), where the impact parameter between the nuclei exceeds the sum of their radii, the final-state particles are predominantly produced back-to-back in the transverse plane, enabling precise and efficient event identification.

Calibration and performance of the ATLAS Tile Calorimeter in Run 3 / Cucinotta, Martina (Universita & INFN Pisa (IT)) ; ATLAS Tile Collaboration /ATLAS Collaboration
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The scintillators are read-out by the wavelength shifting fibres coupled to the photomultiplier tubes (PMTs). [...]

Developments and Performance of ATLAS Electron and Photon Triggers in Run 3 / Duong, Timoty (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
A number of flagship analyses in the ATLAS experiment rely on electron and photon triggers to efficiently record events of interest. During Run 3, these triggers have undergone significant developments, including the integration of advanced machine learning techniques, to achieve high efficiency while controlling background rates and operating within the constraints of the trigger hardware.
