Zimányi School

This reprint includes papers that were presented at the Zimányi School Winter Workshop in 2022. This workshop aimed to summarize the developments of 2022 in high-energy heavy-ion physics with particular attention to the new data emerging from the Relativistic Heavy Ion Collider (RHIC), the Large Hadron Collider (LHC) and SPS. The included papers discuss new results in hydrodynamics, flow and femtoscopy. One of the main aims of the workshop was to encourage interactions between the theoretical and experimental community, hence experimental and theoretical papers appear alongside one another in the reprint.
