AtlFast3: The Next Generation of Fast Simulation in ATLAS / Hasib, Ahmed (The University of Edinburgh (GB)) /ATLAS Collaboration
ATLAS is one of the largest experiments at the Large Hadron Collider. Its broad physics program ranges from precision measurements to the discovery of new interactions, requiring gargantuan amount of simulated Monte Carlo events. [...]

Improvements to ATLAS Inner Detector Track reconstruction for LHC Run-3 / Schillaci, Zachary Michael (Brandeis University (US)) ; Vessella, Makayla (University of Massachusetts (US)) ; Swatman, Stephen Nicholas (University of Amsterdam (NL)) ; Goblirsch-Kolb, Maximilian Emanuel (Brandeis University (US)) ; Cairo, Valentina (SLAC National Accelerator Laboratory (US)) ; Pettersson, Nora Emilia (CERN) /ATLAS Collaboration
This talk summarises the main changes to the ATLAS experiment’s Inner Detector Track reconstruction software chain in preparation of LHC Run 3 (2022-2024). The work was carried out to ensure that the expected high-activity collisions with on average 50 simultaneous proton-proton interactions per bunch crossing (pile-up) can be reconstructed promptly using the available computing resources.

Evolution of ATLAS analysis workflows and tools for the HL-LHC era / Forti, Alessandra (University of Manchester (GB)) ; Cameron, David (University of Oslo (NO)) ; South, David (Deutsches Elektronen-Synchrotron (DE)) ; Klimentov, Alexei (Brookhaven National Laboratory (US)) ; Pacheco Pages, Andreu (The Barcelona Institute of Science and Technology (BIST) (ES)) /ATLAS Collaboration
The High Luminosity LHC project at CERN, which is expected to deliver a ten-fold increase in the luminosity of proton-proton collisions over LHC, will start operation towards the end of this decade and will deliver an unprecedented scientific data volume of multi-exabyte scale. This vast amount of data has to be processed and analysed, and the corresponding computing facilities must ensure fast and reliable data processing for physics analysis by scientific groups distributed all over the world.

Experience with Rucio in the wider HEP community / Barisits, Martin (CERN) ; Beermann, Thomas (Bergische Universitaet Wuppertal (DE)) ; Cameron, David (University of Oslo (NO)) ; Di Maria, Riccardo (CERN) ; Lassnig, Mario (CERN) ; Serfon, Cedric (Brookhaven National Laboratory (US)) ; Vaandering, Eric Wayne (Fermi National Accelerator Lab. (US)) /ATLAS Collaboration
Managing the data of scientific projects is an increasingly complicated challenge, which was usually met by developing experiment-specific solutions. However, the ever-growing data rates and requirements of even small experiments make this approach very difficult, if not prohibitive. [...]

Observation of electroweak production of two jets and a Z-boson pair with the ATLAS detector at the LHC / Zhang, Shuzhou (University of Michigan (US)) /ATLAS Collaboration
The observation of electroweak production of two jets in association with a Z‐ boson pair using 139 fb−1 of pp collision data at √ s = 13 TeV collected by the ATLAS detector at the LHC is reported. Two different final states originating from the decays of the Z boson pair, 4l and 2l2v, are included in the measurements. [...]

Methods of Data Popularity Evaluation in the ATLAS Experiment at the LHC / Grigoryeva, Maria (M.V. Lomonosov Moscow State University (RU)) ; Chuchuk, Olga (Université Côte d'Azur (FR)) ; Sciaba, Andrea (CERN) ; Klimentov, Alexei (Brookhaven National Laboratory (US)) ; Tretyakov, Evgeny (National Research Nuclear University MEPhI (RU)) ; Di Girolamo, Alessandro (CERN) ; Beermann, Thomas (Bergische Universitaet Wuppertal (DE)) ; Schulz, Markus (CERN) ; Lassnig, Mario (CERN) /ATLAS Collaboration
The ATLAS Experiment at the LHC generates petabytes of data that is distributed among 160 computing sites all over the world and is processed continuously by various central production and user analysis tasks. The popularity of data is typically measured as the number of accesses and plays an important role in resolving data management issues: deleting, replicating, moving between tapes, disks and caches.

Measurement of the vector-boson transverse momentum distributions with ATLAS / Pudzha, Dennis (NRC Kurchatov Institute PNPI (RU)) /ATLAS Collaboration
The transverse momentum distribution of W/Z bosons produced in hadronic collisions is a traditional probe of strong interaction dynamics. The correct modelling of this distribution is important in many physics analyses at the LHC for which the production of W or Z bosons constitutes a significant background. [...]
