Summary of new ATLAS results from BOOST 2023
31 July 2023 | By
The 15th International Workshop on Boosted Object Phenomenology, Reconstruction, Measurements, and Searches at Colliders (BOOST 2023) kicks off today in Lawrence Berkeley National Lab, California (USA). The conference brings together experts from the LHC experiments and the theory community to discuss new approaches for using “jets” of particles in studies of Quantum Chromodynamics (QCD) and searches for physics beyond the Standard Model.
The ATLAS Collaboration will be unveiling several new results at BOOST 2023, including new studies showcasing different applications of machine learning in jet tagging. Key results will be explored in ATLAS Physics Briefings, to be released throughout the conference. Check the BOOST 2023 tag for the latest updates. The full list of new ATLAS results presented at BOOST 2023 is given below.
