Summary of new ATLAS results from Moriond 2024
22 March 2024 | By
This year, the start of Spring marks the beginning of the conference season for particle physicists! All eyes turn to La Thuile, Italy, where the annual Recontres de Moriond conferences will be held. Starting on 24 March with the Electroweak Interactions & Unified Theories conference, followed by the QCD and High Energy Interactions conference on 31 March, these gatherings bring together theorists and experimentalists from around the world to share their latest findings.
ATLAS Collaboration members will be at the forefront, unveiling new analyses of the full LHC Run-2 dataset (collected 2015-2018) and diving into studies of the Run-3 dataset (2022-ongoing). Look forward to measurements of key Standard-Model parameters, novel searches for new heavy particles, precision studies of familiar particles and more.
Several of these ATLAS analyses will be featured in upcoming physics briefings, with many more presented in conference talks. Keep up with the latest by following the 2024 Moriond conference tag. Explore the full list of new ATLAS results below, which will be updated as the conferences progress.
