ATLAS Inner Tracker Upgrade Pixel Detector / Molinatti, Umberto (University of Oxford (GB)) /ATLAS Collaboration
In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). [...]

The ATLAS Run-3 Trigger Menu / Cella, Sofia (CERN) /ATLAS Collaboration
The ATLAS experiment in the LHC Run 3 is recording up to 3 kHz of fully-built physics collision events out of an LHC bunch crossing rate of up to 40 MHz, with additional rate dedicated to partial readout. A two-level trigger system selects events of interest to to cover a wide variety of physics while rejecting a high rate of background events. [...]

ATLAS Level-1 Trigger Menu Testing / Penc, Ondrej (CERN) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS experiment, located at the LHC at CERN, requires a flexible and comprehensive Level-1 Trigger configuration to meet its diverse scientific goals. A robust framework, presented in this contribution, validates such a configuration throughout every year of data-taking. [...]

Novell trigger strategies for HL-LHC in ATLAS / Geralis, Theodoros (Nat. Cent. for Sci. Res. Demokritos (GR)) /ATLAS Collaboration
The ATLAS experiment at CERN is constructing upgraded system for the "High Luminosity LHC", with collisions due to start in 2029. 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 [...]

Commissioning and evolution of the Run 3 ATLAS Trigger / Nobe, Takuya (University of Tokyo (JP)) /ATLAS Collaboration
The ATLAS experiment in the LHC Run 3 uses a two-level trigger system to select events of interest to reduce the 40 MHz bunch crossing rate to a recorded rate of up to 3 kHz of fully-built physics events. The trigger system is composed of a hardware based Level-1 trigger and a software based High Level Trigger. [...]

GELATO: a Generic Event-Level Anomalous Trigger Option for ATLAS - Slides / Cohen, Max Michael (University of Pennsylvania (US)) ; Addepalli, Sagar (SLAC National Accelerator Laboratory (US)) ; Gonski, Julia Lynne (SLAC National Accelerator Laboratory (US)) ; Gugel, Ralf (Johannes Gutenberg Universitaet Mainz (DE)) ; Jia, Kenny (SLAC National Accelerator Laboratory (US)) ; Rankin, Dylan Sheldon (University of Pennsylvania (US)) ; Shahinian, Jeff (University of Pennsylvania (US)) ; Martinez Suarez, Paula (CERN) ; Sugizaki, Kaito (University of Pennsylvania (US)) /ATLAS Collaboration
Anomaly detection (AD), a set of machine learning methods that flout minimal model dependence, have continued to gain popularity in the ATLAS experiment as we search for new physics. While current AD analyses have produced exciting results, it remains a possibility that such new physics evades the standard set of triggers. [...]

ATLAS Muon Detectors upgrades 
for High Luminosity LHC / Sessa, Marco (University Federico II and INFN, Naples (IT)) /ATLAS Collaboration
The muon spectrometer of the ATLAS detector will undergo a substantial upgrade during the Phase-II upgrade in Long Shutdown 3 to meet the operational demands of the High-Luminosity LHC. Most of the electronics for the Monitored Drift Tube (MDT) chambers, Resistive Plate Chambers (RPC), and Thin Gap Chambers (TGC) will be replaced to ensure compatibility with the higher trigger rates and extended latencies required for the new level-0 trigger.

Constraining the Higgs boson width from Higgs-top Yukawa coupling at the ATLAS experiment / Zhang, Yangfan (University of Science and Technology of China (CN)) /ATLAS Collaboration
The discovery of the Higgs boson, made by the ATLAS and CMS Collaborations at CERN’s Large Hadron Collider (LHC) in 2012, has opened a new era of measuring the Higgs boson properties to test the SM and search for new physics. The width of Higgs boson, predicted in SM as 4 MeV assuming a Higgs mass of 125 GeV, is a fundamental property that can be sensitive to the potential new physics beyond the SM. [...]
