Results from the recent 2025 light ion LHC run by ALICE, ATLAS, CMS and LHCb

Tuesday 16 Sept 2025, 10:30 → 12:30 Europe/Zurich

500/1-001 - Main Auditorium (CERN)

Tancredi Carli (CERN), Jan Fiete Grosse-Oetringhaus (CERN)

In July 2025, LHC injected for the first time Oxygen and Neon. Motivated by physics questions of the heavy-ion and cosmic-ray community, Oxygen-Oxygen, Neon-Neon and proton-Oxygen collisions took place. The seminar reviews the first results of ALICE, ATLAS, CMS and LHCb. The data are used to study the emergence of collective phenomena and the presence of parton energy loss in small collision systems as well as to study particle production important for understanding processes happening when cosmic rays hit the earth’s atmosphere.
