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…

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…

Chiral Sigma Model with Pion Mean Field in Finite Nuclei
Y. Ogawa, H. Toki, S. Tamenaga +4
The properties of infinite matter and finite nuclei are studied by using the chiral sigma model in the framework of the relativistic mean field theory. We reconstruct an extended c…
