Exotic Quarkonia in Heavy-ion Collisions

2 Feb 2026, 09:00 → 6 Feb 2026, 17:00 Europe/Berlin

02.430 (Mainz Institute for Theoretical Physics, Johannes Gutenberg University)

The registration for this event closed on 09 October 2025, 11:59 pm CET.

 

This topical workshop will bring together leading theorists and experimentalists to explore the world of exotic quarkonia, hadrons made of two heavy quarks whose structure challenges the conventional quark model. Recent observations of these states in heavy-ion collisions open new avenues to study their nature and the properties of the quark-gluon plasma, a state of matter created in these collisions. 
  The workshop will foster collaboration between experts in exotic and conventional quarkonium physics, both theorists and experimentalists, and it aims to develop innovative approaches to analyze current and upcoming data and refine the current theoretical models. The program will feature dedicated sessions with presentations of the latest experimental and theoretical advances, and round table discussions.
