Quark Matter is the largest conference in the field of ultra-relativistic heavy ion collision physics and the study of quark and gluon plasma. It was held from April 6 to 12, 2025, in Frankfurt, Germany (https://indico.cern.ch/event/1334113/) and brought together more than 1,000 physicists in the field.

The Subatech Plasma team presented the latest preliminary results from ALICE Run 3, including Victor Valencia's results on the first measurement of the elliptic flow of J/Psi in Pb-Pb collisions at 5. 36 TeV using the cumulant method (poster) and Emilie Barreau's results on the separation of prompt and non-prompt contributions of J/psi in proton-proton collisions at forward momentum using the MFT (Muon Forward Tracker) (poster). These were highlighted in the plenary review presentations. Maurice Coquet also presented theoretical work on the study of the angular distribution of lepton pairs produced in ultrarelativistic heavy ion collisions as a probe of quark-gluon plasma thermalization (presentation).

From the Theory team, Jiaxing Zhao presented recent advances within EPOS4 on the production of heavy flavors and quarkonia in pp (presentation), while Pol Bernard Gossiaux presented the work of Aoumeur Daddi Hammou dedicated to a generalized Linblad equation (poster). Finally, Greg Jackson (photo) presented a plenary session on the state of the art in theoretical advances in electroweak emission in heavy ion collisions (presentation).
