properties of nuclear matter
   [PDF]

Ju-Hyun Jung, Ulugbek T. Yakhshiev, Hyun-Chul Kim
We investigate the bulk properties of symmetric nuclear matter within the framework of an in-medium modified chiral solitonic model with $\pi$, $\rho$ and $\omega$ mesons. We consider the modification of meson degrees of freedom in nuclear matter, based on phenomenology of pion-nucleus scattering and the empirical nuclear mass formula. We discuss the results of the density dependence of the volume term in the mass formula and the incompressibility of symmetric nuclear matter, comparing them with relativistic mean-field models. The mass dropping of the $\rho$ meson in nuclear matter is also obtained and discussed.
