In the present paper, the current efforts in heavy-ion collisions toward high-density nuclear matter will be discussed. First, the essential points learned from RHIC and LHC will be reviewed. Then, the present data from the STAR Beam Energy Scan are discussed. Finally, the current efforts, NICA, FAIR, HIAF, and J-PARC-HI (heavy ion) are described. In particular, the efforts of the J-PARC-HI project are described in detail.

"Liquid gold" has been traditionally used for over a century to decorate ceramicware, but its chemical composition has not been thoroughly investigated. One of the keys to successfully characterizing liquid gold, which is a complex mixture, is to distinguish Au-containing products from other chemicals. In this paper, we propose a separation based on the difference in collision cross section, of which chemicals with heavy atoms are relatively smaller than those without in ion mobility-mass spectrometry (IM-MS).

Λ = Λ(1405) plays an essential role in the formation of kaonic nuclear clusters (KNC). The simplest KNC, Kpp, has the structure Λp = (Kp)p, in which a real kaon migrates between two nucleons, mediating super-strong Λp attraction. Production data of Kpp have been accumulated by DISTO, J-PARC E27 and J-PARC E15 experiments.

Utilizing a comprehensive (3+1)D relativistic hydrodynamic framework with multiple conserved charge currents and charge-dependent lattice-QCD-based equation of state, we study the baryon and electric charge number deposition at midrapidity in isobar Ru+Ru and Zr+Zr collisions at the center of mass energy sqrt[s_{NN}]=200 GeV. Comparing our predictions with upcoming experimental data from the Relativistic Heavy Ion Collider will shed light on the existence of baryon junctions.
