Searches for Higgs boson pair production in the ATLAS experiment / Ferrari, Arnaud (Uppsala University (SE)) /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. [...]

Overview of ATLAS muon detectors: status and performance / Izumiyama, Shota (Nagoya University (JP)) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS Muon Spectrometer, the largest muon system ever built at colliders, now comprises both legacy gaseous detectors—Monitored Drift Tubes (MDT), Thin Gap Chambers (TGC), and Resistive Plate Chambers (RPC)—which have been in operation for over 15 years, as well as newer technologies like Micromegas and small-strip TGCs in the NSW. These new systems are now in stable operation following an extensive phase of construction and commissioning, providing enhanced muon tracking and trigger capabilities. [...]

ATLAS Tile calorimeter: Performance and upgrade for HL-LHC conditions / Tropina, Anastasiia (Joint Institute for Nuclear Research (RU)) /ATLAS Collaboration
The Tile Calorimeter (TileCal) is the hadronic calorimeter covering the central region of the ATLAS experiment, which measures energies in range from about 30 MeV to about 2 TeV. TileCal is a sampling calorimeter with steel as absorber and scintillators as active medium. [...]

GELATO: A Generic Event-Level Anomalous Trigger Option for ATLAS / Addepalli, Sagar (SLAC National Accelerator Laboratory (US)) /ATLAS Collaboration
The absence of beyond-Standard-Model physics discoveries at the LHC suggests that new physics may evade conventional trigger strategies. The existing ATLAS triggers are required to control data collection rates with high energy thresholds and target signal topologies specific to only certain models. [...]

Searches for supersymmetry in non-minimal models with ATLAS / Nguyen, Hoang Dai Nghia (Universite de Montreal (CA)) /ATLAS Collaboration
Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. With increasing mass bounds on MSSM scenarios other non-minimal variations of supersymmetry become increasingly interesting. [...]

Production and Quality Control of the ITk Pixel Outer Endcap Local Supports for the High-Luminosity upgrade of the ATLAS detector / ATLAS Collaboration
The ATLAS experiment will be upgraded with a new Inner Tracker (ITk) detector for the High-Luminosity phase of the Large Hadron Collider. The ITk, a fully silicon-based detector, will replace the current Inner Detector, enhancing its tracking performance through increased acceptance and improved spatial and time resolution. [...]

Jet flavour tagging at ATLAS with GN3 / Biswas, Diptaparna (Universitaet Siegen (DE)) /ATLAS Collaboration
Accurate identification of jets that originate from heavy-flavour hadrons is pivotal for many ATLAS analyses, from Higgs-boson and top-quark measurements to searches for new physics. We present GN3, the newest heavy-flavour tagger, which introduces a full-transformer architecture tailored to the environment of Run 2 and Run 3. [...]

Challenges in experimental measurements of quantum properties at the LHC / Jones, Eleanor (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
This talk highlights the challenges faced when attempting to measure quantum properties. In particular, difficulties in the identification of jet flavours and the reconstruction of ttbar systems will be considered, especially in the boosted topology where the decay products become highly collimated..

Orchestrating Quasi-Real Time Data Processing in the Computing Farm of the ATLAS Experiment at CERN / Avolio, Giuseppe (CERN) /ATLAS Collaboration
What has Kubernetes got to do with a High Energy Physics experiment collecting one million physics events per second at a data rate of 5 TB/s? That is what we would like to show you! The ATLAS experiment at CERN filters one million complex collision signatures per second provided by the Large Hadron Collider in quasi real-time, using a mixture of custom electronics and a large computing farm (the Event Filter – EF – farm) consisting of up to 5000 commodity servers. In this talk, we will tell you how we are going to exploit Kubernetes to orchestrate the ATLAS EF computing farm. [...]

The impact of Artificial Intelligence on precision Higgs Boson physics / Rousseau, David (Université Paris-Saclay (FR)) /ATLAS Collaboration
Particle physics has a rich history of developing advanced simulators, ranging from modelling proton collisions to creating virtual detectors. We are now integrating Artificial Intelligence through "Neural Simulation Based Inference," which enables the analysis of complex phenomena that cannot be computed analytically from first principles.
