Development of the ATLAS Liquid Argon Calorimeter Off-detector Readout Electronics for the HL-LHC / Helbig, Markus (Technische Universitaet Dresden (DE)) /ATLAS Collaboration
The High-Luminosity LHC will start operations for physics in 2029, allowing to collect ten times more data than what have been achieved by the LHC. This expansion of the dataset will be achieved by increasing the number of collisions per bunch crossing, leading, however, to higher radiation doses and busier events. [...]

Machine Learning for Real-Time Processing of ATLAS Liquid Argon Calorimeter Signals with FPGAs / Voigt, Johann Christoph (Technische Universitaet Dresden (DE)) /ATLAS Collaboration
The Phase-II Upgrade of the LHC will increase its instantaneous luminosity by a factor of 7 leading to the High Luminosity LHC (HL-LHC). At the HL-LHC, the number of proton-proton collisions in one bunch crossing (called pileup) increases significantly, putting more stringent requirements on the LHC detectors electronics and real-time data processing capabilities.

Development of the ATLAS Liquid Argon Calorimeter On-detector Readout Electronics for the HL-LHC / Dartois, Jules (Université Paris-Saclay (FR)) ; ATLAS LAr Collaboration ; Kersevan, Borut Paul (Jozef Stefan Institute (SI)) /ATLAS Collaboration
The High-Luminosity LHC will start operations for physics around 2030, allowing to collect ten times more data than what will have been achieved by the LHC. This expansion of the dataset will be achieved by increasing the number of collisions per bunch crossing, leading, however, to higher radiation doses and busier events [...]

Technical challenges and performance of the new ATLAS LAr Calorimeter Trigger / Yang, Yi-Lin (Southern Methodist University (US)) /ATLAS Collaboration
The Liquid Argon Calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. They also provide inputs to the first level of the ATLAS trigger. [...]

Searches for unusual signatures in hadronic channels with the ATLAS detector / Scholer, Patrick (Carleton University (CA)) /ATLAS Collaboration
Various theories beyond the Standard Model predict new, long-lived particles with unique signatures involving jets, which are difficult to reconstruct and for which estimating the background rates is also a challenge. These include emerging jets, semi-visible, and soft unclustered energy patters [...]

The ATLAS Forward Proton (AFP) sub-detector and the adverse effects of radiation from Large Hadron Collider (LHC) collimators during p-p collisions at 13.6 TeV / Milovanovic, Marko (Justus-Liebig-Universitaet Giessen (DE)) /ATLAS Collaboration
The ATLAS Forward Proton (AFP) sub-detector, located in the forward region of ATLAS experiment (between ~205m and 218m from ATLAS Interaction point) and also near the closest aperture defining collimators (TCL6, ~219m from IP1) within the Large Hadron Collider (LHC), has encountered significant operational challenges during p-p collisions at 13.6 TeV (Run-3) due to excessive and increasing radiation exposure with higher integrated luminosity being delivered to ATLAS. This study analyses the negative impact of this proximity on AFP electronics and various detector components, but also on the personnel involved in detector maintenance and failing component replacement during short accesses.

Automatizing the search for mass resonances using BumpNet / ATLAS Collaboration
The search for resonant mass bumps in invariant-mass histograms is a fundamental approach for uncovering Beyond the Standard Model (BSM) physics at the Large Hadron Collider (LHC). Traditional, model-dependent analyses that utilize this technique, such as those conducted using data from the ATLAS detector at CERN, often require substantial resources, which prevent many final states from being explored.

The ATLAS detector at CERN’s Large Hadron Collider (LHC) is a complex system composed of multiple subdetectors, each designed to capture complementary aspects of particle interactions. Thus, accurate understanding of the physical phenomena under study requires effectively combining information from these components. [...]

An Implementation of Neural Simulation-Based Inference for Parameter Estimation at the LHC / Sandesara, Jay Ajitbhai (University of Wisconsin Madison (US)) /ATLAS Collaboration
Neural simulation-based inference is a powerful class of machine-learning-based methods for statistical inference that naturally handles high-dimensional parameter estimation without the need to bin data into low-dimensional summary histograms. Such methods are promising for a range of measurements, including at the Large Hadron Collider, where no single observable may be optimal to scan over the entire theoretical phase space under consideration, or where binning data into histograms could result in a loss of sensitivity.

Recent Heavy Flavor Results in ATLAS / Gentry, Andrew Donald (University of New Mexico (US)) /ATLAS Collaboration
Studying heavy-flavour hadron properties provides a extensive tests for various QCD predictions as well as a means to probe the Standard Model validity. ATLAS experiment, being a general-purpose detector at LHC, is particularly successful in such measurements with final states involving muons, thanks to large collected integrated luminosity and precise muon reconstruction and triggering.
