Dear Colleagues,

We would like to invite you to participate in this year's workshop that aims to summarize the developments of 2018 in high energy heavy ion physics, with particular attention to the new data emerging from the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), SPS and J-PARC. We will discuss results from other high energy nuclear and particle physics facilities of the world, most importantly lower energy colliders, exploring the nuclear phase diagram (with special attention to FAIR and NICA). Another important point of the School is to discuss important new results in hydrodynamics, flow and femtoscopy. One of the main aims of the School is to encourage interaction between the theoretical and experimental community. A slightly overlapping list of topics of the School includes (in alphabetical order):

Effective QCD theory/model approaches
Elastic scattering and diffraction (experiment+theory)
Femtoscopy (experiment+theory)
Flow and hydrodynamics (experiment+theory)
Gluon saturation and electron-ion collider (experiment+theory)
Heavy flavor and quarkonia (experiment+theory)
Intermediate energies (FAIR, J-PARC, nuclear physics)
Jets and high pT probes (experiment+theory)
Magnetic field in heavy ion collisions (experiment+theory)
Photons and dileptons (experiment+theory)
QCD at non-zero temperature and density
Search for the QCD critical point (experiment+theory)
Strongly coupled gauge theories (beyond SM, AdS/CFT)
Vorticity and polarization in heavy ion physics (experiment+theory)

We are looking forward to the continuation of this series and hope to welcome our colleagues and friends in Hungary.
