Progress of study on the properties of nuclear matter with high baryon density at CSR energy region

This review is focused on the low energy part of the QCD phase diagram, the properties of the nuclear matter with high baryon density which could be experimentally studied at the large scale facility for nuclear physics in China, such as the split of nucleon effect mass, symmetric energy of high baryon density nuclear matter, the properties of hadrons in the nuclear medium. The properties of nuclear matter with high baryon density and the resonance states of hadron have been studied theoretically and some physical observables related to the properties of nuclear matter with high baryon density are pointed out under the heavy ion collisions with the energy at the region of 0.5–1.2 GeV/u. The existing experimental setup at HIRFL-CSR has been improved and a test experiment has been performed. The results show the ability to explore the properties of the nuclear matter with high baryon density. Our studies are helpful to design and built a professional spectrometer for the low energy part of the QCD phase diagram in the near future.
