The properties of η-nucleus interaction and their experimental consequences are investigated with η-nucleus optical potentials obtained by postulating the N * (1535) dominance for η-N system. The N * (1535) properties in nuclear medium are evaluated by two kinds of chiral effective models based on distinct pictures of N * (1535). We find that these two models provide qualitatively different opt...

We present a theoretical study on formation rates of η and ω meson-nucleus systems induced by (γ, p) reactions on nuclear targets at ideal recoilless condition. We find that the smaller distortion effect in the (γ, p) reaction enables us to investigate properties of the mesons created deeply inside nucleus more clearly. We also consider excitation of scalar-isoscalar (σ) mode in nucleus in orde...

Using an isospin-dependent transport model for heavy-ion collisions induced by neutron-rich nuclei at intermediate energies, we study the production of light clusters such as deuteron, triton, and He via coalescence of nucleons. We find that both the yields and energy spectra of these light clusters are affected significantly by the density dependence of nuclear symmetry energy, with a stiffer ...
