The Relativistic Heavy Ion Collider (RHIC) in Brookhaven National Laboratory are currently searching for the novel phenomena of chirality and criticality. The isobaric collision experiment, contrasting the RuRu and ZrZr colliding systems, is specifically designed to probe potential signals of the Chiral Magnetic Effect (CME), that will be the crucial test for the topological aspects of QCD and other associated phenomena. The Beam Energy Scan II (BES II) aim to provide decisive discovery of critical fluctuations of the QCD critical point (QCDCP), the existence of which is one of the fundamental questions in nuclear physics emphasized in the 2015 NSAC Long Range Plan. Moreover, the 27 GeV Au-Au experiments is dedicated to explore global spin polarization of Lambda hyperons, that is a fascinating evidence of the vorticity of the created plasma and the quantum spins of its constituents.

This 4-week program will gather theorists and experimentalists working on these novel many-body phenomena and related subjects in heavy-ion collisions, also including realistic simulations of heavy-ion collisions as well as recent developments in lattice QCD equation of states pertinent to these subjects. We plan to have a flexible program schedule, with these topics discussed and mixed together in each of the weeks 1, 3 and 4. We will organize the talks and discussions according to the main themes listed below. In week 2 (May 18-22), we will host a full-week workshop broadly open to related fields of study, that is jointly supported by the Beam Energy Scan Theory (BEST) topical collaboration. A workshop registration fee may apply. The registration fee includes participation in the workshop, lectures, and coffee breaks.
