Relativistic Chiral Mean Field Model for Finite Nuclei
Yoko Ogawa, Hiroshi Toki, Setsuo Tamenaga +1
We present a relativistic chiral mean field (RCMF) model, which is a method for the proper treatment of pion-exchange interaction in the nuclear many-body problem. There the domina…
Coleman-Weinberg mechanism for spontaneous chiral symmetry breaking in the massless chiral sigma model
Setsuo Tamenaga, Hiroshi Toki, Akihiro Haga +1
We study the effect of one-loop corrections from nucleon together with those from boson in the massless chiral sigma model, where we perform the Coleman-Weinberg renormalization pr…
Collective excitations and energy-weighted sum rules in relativistic random phase approximation with vacuum polarization
A. Haga, H. Toki, S. Tamenaga +1
The isoscalar and isovector collective multipole excitations in stable nuclei are studied in the framework of relativistic random-phase approximation with the vacuum polarization a…
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…
