EW and QCD Measurements / Cardoso Silva, Julia Manuela (The University of Edinburgh (GB)) /ATLAS Collaboration
Precise measurements with the ATLAS and CMS experiments at the LHC are used to determine fundamental parameters of the Standard Model, and provide stringent tests of the electroweak theory and perturbative QCD. In this talk, extraordinarily precise double-differential measurement of the Z boson in the full phase space of the decay leptons at a centre-of-mass energy of 8 TeV are discussed. [...]

Search for dark mesons decaying to top and bottom quarks with the ATLAS detector / Heinrich, Jochen Jens (University of Oregon (US)) /ATLAS Collaboration
The Standard Model can be extended by a new strongly-coupled, SU(2) dark flavour symmetry conserving model that gives rise to a familiar-looking dark sector as direct analogue to the QCD meson and baryon sector. Dark matter could thus manifest itself as composite dark mesons free of constraints from precision Higgs coupling or electroweak measurements. [...]

Deployment of ATLAS Calorimeter Fast Simulation Training Through Container Technology / Corchia, Federico Andrea (Universita e INFN, Bologna (IT)) ; Rinaldi, Lorenzo (Universita e INFN, Bologna (IT)) ; Faucci Giannelli, Michele (INFN e Universita Roma Tor Vergata (IT)) ; Zhang, Rui (University of Wisconsin Madison (US)) ; Beirer, Joshua Falco (CERN) /ATLAS Collaboration
Simulation of the detector response is a major computational challenge in modern High Energy Physics experiments, as for example it accounts for about two fifths of the total ATLAS computing resources. Among simulation tasks, calorimeter simulation is the most demanding, taking up about 80% of resource use for simulation and expected to increase in the future. [...]

AtlFast3: Fast Simulation in ATLAS for LHC Run 3 and beyond / Beirer, Joshua Falco (CERN) /ATLAS Collaboration
As we are approaching the high-luminosity era of the LHC, the computational requirements of the ATLAS experiment are expected to increase significantly in the coming years. In particular, the simulation of MC events is immensely computationally demanding, and their limited availability is one of the major sources of systematic uncertainties in many physics analyses. [...]

Towards a Simplified (Fast) Simulation Infrastructure in ATLAS / Beirer, Joshua Falco (CERN) /ATLAS Collaboration
To increase the number of Monte Carlo simulated events that can be produced with the limited CPU resources available, the ATLAS experiment at CERN uses a variety of fast simulation tools in addition to the detailed simulation of the detector response with Geant4. The tools are deployed in a heterogeneous simulation infrastructure known as the Integrated Simulation Framework (ISF), which was originally developed over a decade ago. [...]

Boosting CPU Efficiency in ATLAS Inner Detector Reconstruction with Track Overlay / Tsai, Fang-Ying (Stony Brook University (US)) ; Duda, Dominik (The University of Edinburgh (GB)) ; Jiggins, Stephen (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
In response to the rising CPU consumption and storage demands, as we enter a new phase in particle physics with the High-Luminosity Large Hadron Collider (HL-LHC), our efforts are centered around enhancing the CPU processing efficiency of reconstruction within the ATLAS inner detector. The track overlay approach involves pre-reconstructing pileup tracks and subsequently running reconstruction exclusively on hard-scatter tracks. [...]

Fatras integration for ATLAS fast simulation at HL-LHC / Mijovic, Liza (The University of Edinburgh (GB)) ; Wang, Rui (Argonne National Laboratory (US)) ; Javurkova, Martina (University of Massachusetts (US)) ; Chapman, John Derek (University of Cambridge (GB)) ; Shemyakin, Dmitry (Weizmann Institute of Science (IL)) /ATLAS Collaboration
The computing challenges in collecting, storing, reconstructing, and analyzing the colossal volume of data produced by the ATLAS experiment and producing similar numbers of simulated Monte Carlo (MC) events put formidable requirements on the computing resources of the ATLAS collaboration. ATLAS currently expends around 40% of its CPU resources on detector simulation, in which half of the events are produced with full simulation using GEANT4. [...]

A Function-as-a-Task Workflow Management Approach with PanDA and iDDS / ATLAS Collaboration
The growing complexity of high energy physics analysis often involves running a large number of different tools. This demands a multi-step data processing approach, with each step requiring different resources and carrying dependencies on preceding steps. [...]

The ATLAS experiment at CERN’s Large Hadron Collider has been using ROOT TTree for over two decades to store all of its processed data. The ROOT team has developed a new I/O subsystem, called RNTuple, that will replace TTree in the near future. [...]
