The environmental impact, carbon and sustainability of computing in the ATLAS experiment / Marshall, Zach (Lawrence Berkeley National Lab. (US)) /ATLAS Collaboration
ATLAS, one of two general-purpose experiments at the Large Hadron Collider (LHC), operates a large internationally-distributed computing infrastructure, including over 1 EB of managed data on disk and tape and almost one million simultaneously running CPU cores. Upgrades for the High-Luminosity LHC will increase the required computing resources by a factor of 3–4 by the beginning of the 2030s, and by an order of magnitude before the conclusion of data taking at the beginning of the 2040s.

Performance Highlights of the ATLAS Detector / Falda Coelho, Luis (Laboratory of Instrumentation and Experimental Particle Physics (PT)) /ATLAS Collaboration
The ATLAS experiment at the Large Hadron Collider (LHC) continues to deliver high-precision measurements and new physics insights through its extensive dataset collected during Run 2 and the ongoing Run 3. The performance of key detector subsystems, including tracking, calorimetry, and muon detection, plays a crucial role in ensuring the accuracy of physics analyses. [...]

SUSY Highlight Talk: Recent results in electroweak searches for compressed spectra / Ballabene, Eric (Universita e INFN, Bologna (IT)) /ATLAS Collaboration
Supersymmetry (SUSY) models featuring small mass splittings between one or more particles and the lightest neutralino could solve the hierarchy problem as well as offer a suitable dark matter candidate consistent with the observed thermal-relic dark matter density. However, the detection of SUSY higgsinos at the LHC remains challenging especially if their mass-splitting is O(1 GeV) or lower. [...]

ttH+tH measurements from ATLAS / Guo, Linghua (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
The study of Higgs boson production in association with one or two top quarks provides a key window into the properties of the two heaviest fundamental particles in the Standard Model, and in particular into their couplings. This talk presents property measurement of Higgs boson, in particular cross section and CP nature, with tH and ttH production in pp collisions collected at 13 TeV with the ATLAS detector using the full Run 2 dataset of the LHC..

The ATLAS Simulation R&D Programme for Run 4 / Novak, Tadej (Jozef Stefan Institute (SI)) /ATLAS Collaboration
Run 4 of the Large Hadron Collider will deliver a significantly larger dataset, which will, in turn, require the production of many more simulated Monte Carlo events. However, computing resources are not expected to scale at the same rate. [...]

ATLAS Upgrades for the High Luminosity LHC / Cai, Huacheng (University of Pittsburgh (US)) /ATLAS Collaboration
While the on-going Run-3 data-taking campaign will provide twice the integrated proton-proton luminosity currently available at the LHC, most of the data expected for the full LHC physics program will only be delivered during the HL-LHC phase. For this, the LHC will undergo an ambitious upgrade program to be able to deliver an instantaneous luminosity of 7.5×1034 cm−2s−1, allowing the collection of more than 3 ab−1 of data at 13.6 (14) TeV.

Recent Non-Hadronic Results from ATLAS / Schimmel Brener, Roy (Weizmann Institute of Science (IL)) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena, such as Z'/W' bosons, and long-lived particles, which decay into leptons. Searches for new physics with such signatures are performed using the ATLAS experiment at the LHC. [...]
