Quantum Chromodynamics (QCD) is the theory of strong interaction for quarks and gluons, namely, describing the dynamics of strongly interacting particles, hadrons and atomic nuclei. QCD explains the origin of dynamically generated masses of hadrons, where, the dynamical masses explain more than 90% of the physical masses of proton, neutron, and baryons that we experimentally observe. Thus, the dynamical mass gives most of the mass and energy of the ordinary matter around us, or the “visible universe”. (Yet, we admit that the universe contains only 5% of ordinary matter and/or energy, 27% of dark matter, and 68% of an unknown “dark energy”.)

Although the present program focuses on this 5% portion of the total energy in the whole universe, the normal matter around us (protons, neutrons, hadrons) is already very interesting, and shows com- plicated phenomena in free space. However, surprisingly even more, the hadrons which compose the normal matter or most of the visible universe, reveal further unexpected, very exciting and rich feature under the environments such as high density and/or temperature. The properties of hadrons in such environments are far remote from our present understanding in terms of the original theory of QCD. Namely, hadrons feel complicated interactions from the surrounding environment, medium, where the interactions should arise from QCD, but very difficult to explain by it. For example, systems under such environments are, cores of heavy nuclei, neutron star and compact star cores, and dense and/or high temperature matter produced in heavy-ion collisions. These are the topics to be discussed through this Focus Program.
