Workshop on Excited Hyperons in QCD Thermodynamics at Freeze-Out (YSTAR2016) Mini-Proceedings

This Workshop brought top experts, researchers, postdocs, and students from high-energy heavy ion interactions, lattice QCDand hadronicphysics communities together. YSTAR2016 discussed the impact of "missing" hyperonresonances on QCD thermodynamics, on freeze-out in heavy ion collisions, on the evolution of early universe, and on the spectroscopy of strange particles. Recent studies that compared lattice QCDpredictions of thermodynamic properties of quark-gluon plasmaat freeze-out with calculations based on statistical hadronresonance gas models as well as experimentally measured ratios between yields of different hadronspecies in heavy ion collisions provide indirect evidence for the presence of "missing" resonances in all of these contexts. The aim of the YSTAR2016 Workshop was to sharpen these comparisons and advance our understanding of the formation of strange hadronsfrom quarks and gluons microseconds after the Big Bangand in todays experiments at LHC and RHIC as well as at future facilities like FAIR, J-PARCand KL at JLab. It was concluded that the new initiative to create a secondary beam of neutral kaons at JLab will make a bridge between the hardron spectroscopy, heavy-ion experiments and lattice QCDstudies addressing some major issues related to thermodynamics of the early universe and cosmology in general.
