Summary of new ATLAS results from ICHEP 2024
18 July 2024 | By
The 2024 International Conference on High Energy Physics (ICHEP) kicks off this week in Prague, Czech Republic. For over 70 years, ICHEP has gathered physicists from around the world to share the latest advancements in particle physics, astrophysics, cosmology, and accelerator science, and to discuss plans for major future facilities.
The ATLAS Collaboration will be unveiling a wide range of new results at ICHEP 2024, delving into the extensive dataset collected during LHC Run 2 (2015-2018) and presenting first-of-their-kind studies of Run 3 data (collection ongoing). Anticipate exciting new studies of the Higgs boson, pioneering searches for elusive magnetic monopoles and other new-physics phenomena, and much more.
Key results will be explored in ATLAS Physics Briefings, with many more presented in conference talks and posters. For all news and physics briefings, follow the ICHEP 2024 tag and explore all of the latest ATLAS results through the links below.
