The twelfth annual conference on Large Hadron Collider physics (LHCP 2024) kicks off today in Boston, USA. This week-long event will feature a detailed review of the latest experimental and theoretical results in collider physics, including several final studies of the LHC Run-2 dataset (collected in 2015-2018) and discussions on future research directions for the high-energy particle-physics community.

Members of the ATLAS Collaboration will be in attendance, presenting several new analyses of the LHC Run-2 dataset alongside early studies of the Run-3 dataset (2022-ongoing). Look forward to innovative new studies of the Higgs-boson pair production, cutting-edge searches for Dark Matter particles, and much more.

Key results will be explored in ATLAS Physics Briefings, to be released throughout the conference. Check the LHCP 2024 tag for the latest updates. The full list of new ATLAS results presented at LHCP 2024 is given below and will be continually updated this week.
