5th International Workshop on Emergent QCD Collectivity Across Scales: From Small System Collisions to Jets

Event start: 2026-06-29 Event end: 2026-06-30 This is an all-day event. Location: 5 rue Sainte-Croix de la Bretonnerie, 75004 Paris Building on the progress of previous meetings, this edition expands the discussion from small collision systems to jets and other multi-scale probes, reflecting the recent evolution of the field. Recent collider measurements have revealed signatures of collectivity in a remarkably wide range of systems, including pp, pA, light-ion, photonuclear, and jet-tagged events. These observations challenge traditional distinctions between small and large systems, soft and hard probes, and initial- and final-state dynamics. A central aim of the workshop is to place these developments within a unified, scale-dependent QCD framework, and to clarify what they reveal about the emergence of many-body dynamics from microscopic strong interactions.
