The 9th Asian Triangle Heavy-Ion Conference (ATHIC 2023) will be held in Hiroshima, Japan, from Monday 24th through Thursday 27th of April, 2023. It will solely be a face-to-face conference, with no remote participation or broadcasting arrangements.

ATHIC 2023 inherits the tradition of the previous conferences held first in Seoul in 2006 and continued in China, India, Japan, and South Korea.  Many physicists from Asian countries have been actively working on both experimental and theoretical sides of heavy-ion collisions.  ATHIC brings them together to discuss various exciting aspects of this field.  We hope to have fruitful discussions among the participants and develop new ideas to press us forward in further understanding of hot and dense QCD matter.  The conference will also provide an excellent opportunity to summarize what we have learned at RHIC and LHC.

ATHIC 2023 will focus on topics including, but not limited to:

  • Initial state and thermal equilibrium
  • Jets and medium response
  • Heavy quarks and quarkonia
  • Electromagnetic probes
  • Collective dynamics
  • Correlations and fluctuations
  • QCD phase diagram and extreme states
  • QGP in small systems
  • Intense field and vorticity
  • Hadron interactions and exotics
  • New theoretical developments
  • Experimental techniques and future programs

The conference comprises plenary, parallel and poster sessions.  We especially encourage students to submit their contributions.

The conference is supported partly by Grant-in-Aid for Scientific Research on Innovative Areas 18H05401 (K. Shigaki) and Grant-in-Aid for Scientific Research (A) 20H00163 (K. Shigaki), also partly by Japan Atomic Energy Agency, Nagasaki Institute of Applies Science, Nagoya University, Osaka University, Riken, University of Tokyo, and University of Tsukuba, and is under the auspices of Hiroshima University.
