Introduction

We are the Heavy-ion Research Group in the Theory Department of the Wigner Research Centre for Physics (part of the Hungarian Research Network) in Budapest, Hungary.

High-energy heavy ion physics involves many branches of physics, so research in this field covers a very broad range of topics. The research directions include the most fundamental concepts of classical and modern thermodynamics, hydrodynamics and quantum theory, as well as perturbative and non-perturbative quantum field dynamics, high-energy nuclear physics, hadronization and hadron phenomenology. Our results contribute to the interpretation of measurements from the largest international experiments (e.g. CERN-LHC, BNL-RHIC), to the prediction of phenomena expected at the planned new facilities (GSI-FAIR, Dubna-NICA), and to the understanding of the processes of the early universe and the internal structure of compact stars.
