Probing neutron-proton dynamics by pions
Probing neutron-proton dynamics by pions
In order to investigate the nuclear symmetry energy at high density, we study the pion production in central collisions of neutron-rich nuclei $^{132}\mathrm{Sn}+^{124}\mathrm{Sn}$ at 300 MeV/nucleon using a new approach that combines antisymmetrized molecular dynamics (AMD) and a hadronic cascade model (JAM). The dynamics of neutrons and protons is solved …
