| Outline of Final Research Achievements |
To investigate the nuclear symmetry energy and the partial restoration of chiral symmetry at high density, we have studied the pion production in the intermediate-energy heavy-ion collisions using the transport model that combines antisymmetrized molecular dynamics (AMD) and a hadronic cascade model (JAM). We understood the mechanism how the emitted pions and delta resonances reflect the dynamics of neutrons and protons that is sensitive to the symmetry energy. We also found the effects of cluster correlations as well as of the high-density symmetry energy on the nucleon dynamics and consequently on the pion ratios.
