At present, our understanding of the non-equilibrium aspects of a relativistic spin fluid is derived from the study of Wigner function coupled with the semiclassical expansion. In our work, we present an exact computation (up to quantum loop corrections) of the Wigner functions for quarks in a field of oscillating pion condensate. The oscillating pion condensate enters the equation of motion...
We report the recent results from the HADES experiment obtained in Au+Au and Ag+Ag collisions at center-of-mass energies per nucleon pair of 2.42 and 2.55 GeV, respectively. In particular, measurements of hadronic and dilepton observables are presented, with focus on particle correlations and prospects for the future experimental program are outlined.
This talk presents an overview of recent findings from the ATLAS experiment using heavy-ion collisions. These include measurements of how energetic jets are produced and modified as they travel through the hot, dense medium known as the Quark-Gluon Plasma (QGP), which is created in collisions between atomic nuclei at near light speed. The results also include studies of softer particles...
Measurements of strange hadron production provide information on the properties of strongly interacting matter and on the mechanisms of particle production in high-energy collisions. The NA61/SHINE experiment at the CERN SPS North Area investigates these processes through a two-dimensional scan in collision energy and system size, covering a wide range of hadronic and nuclear interactions.

NA61/SHINE at the CERN SPS is a multipurpose fixed-target experiment designed for measurements of charged and neutral hadrons. The main physics goals of the NA61/SHINE strong interaction program are to study the properties of the onset of deconfinement and to search for signatures of the critical point of strongly interacting matter. These objectives are pursued by performing a comprehensive...
The concept of spin hydrodynamics is introduced and the newest developments in this field are reviewed.
According to the Color Glass Condensate approach to relativistic heavy-ion collisions, the earliest phase of the collision is a glasma which is made of highly populated gluon fields that can be treated classically. Using a proper time expansion we study analytically various properties of the glasma. In particular, we compute the glasma energy-momentum tensor which allows us to obtain the...
In this talk, I review recent theoretical efforts to understand the excess of charged over neutral kaons measured by the NA61/SHINE collaboration. This excess signals a much larger breaking of isospin symmetry than expected. In particular, the results of hadron resonance gas approach(es) and of the UrQM simulation, as well as considerations involving the electromagnetic interaction and the...
