Variation of hadron masses in nuclear matter in the relativistic Hartree approximation
H. Shen, S. Tamenaga, H. Toki
We study the modification of hadron masses due to the vacuum polarization using the chiral sigma model, which is extended to generate the meson mass by the sigma condensation i…

Relativistic Hartree approach with exact treatment of vacuum polarization for finite nuclei
Akihiro Haga, Setsuo Tamenaga, Hiroshi Toki +1
We study the relativistic Hartree approach with the exact treatment of the vacuum polarization in the Walecka sigma-omega model. The contribution from the vacuum polarization of nu…

Chiral Symmetry and Finite Pion Mean Field in Nuclei
Hiroshi Toki, Yoko Ogawa, Setsuo Tamenaga +2
We introduce the chiral symmetry in the description of finite nuclei with the hope to unify the hadron and nuclear physics. This trial becomes possible by introducing finite pion m…
