Summary of new ATLAS results from 2023 summer conferences
17 July 2023 | By
The summer conference season is here! While for some, summer means slowing down – for ATLAS researchers, it means the start of new conferences, with more new results to be presented! This season, experimental physics and theorists travel to Melbourne, Australia, for the International Symposium on Lepton Photon Interactions at High Energies (Lepton Photon, 17-21 July 2023), and to Hamburg, Germany, for the European Physical Society Conference on High Energy Physics (EPS-HEP, 21-25 August 2023). Both conferences cover a wide range of topics, from dark matter and Higgs physics, to searches for new physics and astroparticle observations.
The ATLAS Collaboration will be unveiling several new analyses of the LHC Run-2 dataset (collected 2015-2018) and early physics results using the Run-3 dataset (2022-ongoing). Look forward to new studies of the Higgs boson, novel searches for supersymmetry, and much more.
Key results will be explored in ATLAS Physics Briefings released throughout the conferences. Check the 2023 Summer Conferences tag for the latest updates. Explore the full list of new ATLAS results in the links below, which will be updated as the meetings progress.
