Dynamics of Hot QCD Matter -- Current Status and Developments

The discovery and characterization of hot and dense QCD matter, known asQuark Gluon Plasma (QGP), remains the most international collaborative effortand synergy between theorists and experimentalists in modern nuclear physics todate. The experimentalists around the world not only collect an unprecedentedamount of data in heavy-ion collisions, at Relativistic Heavy Ion Collider(RHIC), at Brookhaven National Laboratory (BNL) in New York, USA, and the LargeHadron Collider (LHC), at CERN in Geneva, Switzerland but also analyze thesedata to unravel the mystery of this new phase of matter that filled a fewmicroseconds old universe, just after the Big Bang. In the meantime,advancements in theoretical works and computing capability extend our wisdomabout the hot-dense QCD matter and its dynamics through mathematical equations.The exchange of ideas between experimentalists and theoreticians is crucial forthe progress of our knowledge. The motivation of this first conference named"HOT QCD Matter 2022" is to bring the community together to have a discourse onthis topic. In this article, there are 36 sections discussing various topics inthe field of relativistic heavy-ion collisions and related phenomena that covera snapshot of the current experimental observations and theoretical progress.This article begins with the theoretical overview of relativisticspin-hydrodynamics in the presence of the external magnetic field, followed bythe Lattice QCD results on heavy quarks in QGP, and finally, it ends with anoverview of experiment results.
