Quark Matter 2025 is the XXXI International Conference on Ultra-relativistic Nucleus-Nucleus Collisions, which will be held in Frankfurt, Hesse, Germany. This conference brings together theoretical and experimental physicists from around the world to discuss new developments in high-energy heavy-ion physics. The focus of the discussions is on the fundamental understanding of strongly-interacting matter at extreme conditions, as formed in ultra-relativistic nucleus-nucleus collisions, as well as on emergent QCD phenomena in high-multiplicity proton-proton and proton-nucleus collisions.
The scientific program will cover the following topics:
- 
Chirality
 - 
Collective dynamics & small systems
 - 
Correlations & fluctuations
 - 
Detectors & future experiments
 - 
Electromagnetic probes
 - 
Heavy flavor & quarkonia
 - 
Initial state of hadronic and electron-ion collisions & nuclear structure
 - 
Jets
 - 
Light and strange flavor physics & nuclei
 - 
New theoretical developments
 - 
Physics of ultraperipheral collisions
 - 
QCD matter in astrophysics
 - 
QCD phase diagram & critical point
