Long term aging test of the new PMTs for the HL-LHC ATLAS hadron calorimeter upgrade / Di Gregorio, Giulia (Universita & INFN Pisa (IT)) /ATLAS Collaboration
The central hadronic Tile calorimeter (TileCal) of the ATLAS experiment, is read out by approximately 10,000 photomultipliers (PMT). Earlier PMT performance test results have shown a degradation in response due to the integrated anode charge, with projected losses exceeding 25% for approximately 8% of the photomultipliers, corresponding to the most-exposed TileCal cells, which are expected to integrate charges up to 600 C over the High-Luminosity Large Hadron Collider program.

Effective Field Theory interpretations of ATLAS measurements / Burgard, Carsten Daniel (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
In the absence of direct observations of new physics beyond the Standard Model, interpretations of results using Effective Field Theories can be a powerful tool to place near-model-independent constraints on new physics scenarios, or better observe deviations from the Standard Model and have it interpreted in terms of specific new interactions. This talk presents Effective Field Theory interpretations of individual and combined results from the ATLAS experiment..

Searches for low- and high-mass resonances with the ATLAS detector / Barak, Liron (Tel Aviv University (IL)) /ATLAS Collaboration
Several theories beyond the Standard Model predict the existence of new particles decaying into pairs of gauge bosons. These states generally have masses larger than that of the Higgs boson, while some theories predict resonances with masses smaller than it. [...]

Search for Higgs boson pair production in the bbtautau final state with the ATLAS detector / Deutsch, Christopher (University of Bonn (DE)) /ATLAS Collaboration
The discovery of the Higgs boson and the measurement of its properties confirming the Standard Model (SM) is a major step towards the understanding of electroweak symmetry breaking. As a result, the potential of the Higgs field, and therefore the self-coupling of the Higgs boson, is precisely predicted in the SM. [...]

The Prototype Hardware Design and Test of Global Common Module for Global Trigger System of the ATLAS Phase II Upgrade / Tang, Shaochun (Brookhaven National Laboratory (US)) ; Bonini, Filiberto (Brookhaven National Laboratory (US)) ; ATLAS TDAQ Collaboration /ATLAS Collaboration
The HL-LHC [1] is expected to start operations in the middle of 2027, to deliver more than ten times the integrated luminosity of the LHC Runs 1-3 combined (up to 4000 fb−1). Meeting these requirements poses significant challenges to the hardware design of Trigger and Data Acquisition system. [...]

MACHINE LEARNING FOR REAL-TIME PROCESSING OF ATLAS LIQUID ARGON CALORIMETER SIGNALS WITH FPGAS / Chiedde, Nemer (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
The ATLAS experiment at CERN measures energy of proton–proton (P-P) collisions with a repetition frequency of 40 MHz at the Large Hadron Collider (LHC). The readout electronics of liquid-argon (LAr) calorimeters, developed by ATLAS, are being readied for high luminosity-LHC (HL-LHC) operation as part of the phase-II upgrade, anticipating a pileup of up to 200 simultaneous proton–proton interactions.
