The effective ω-meson mass with a vector field self-interaction
Katsuaki Sakamoto, Hiroaki Kouno, Akira Hasegawa +1
We calculate the effective mass m_ω^* of the ω-meson in nuclear medium by the σ-ωmodel with a vector field self-interaction (VFSI). We found that the direct and the indirect effect…
Effective Vector Meson Masses in a Cutoff Field Theory
K. Sakamoto, M. Nakai, H. Kouno +2
Based on quantum hadrodynamics with a finite cutoff, the effective masses of vector mesons(ω, ρ) in nuclear medium are calculated. We use a low-energy effective Lagrangian which is…
Vacuum Effects and Compressional Properties of Nuclear Matter in Cutoff Field Theory
Hiroaki Kouno, Katsuaki Sakamoto, Yoshitaka Iwasaki +5
Including the vacuum effects, the compressional properties of nuclear matter are studied in the cutoff field theory. Under the Hartree approximation, the low-energy effective Lagra…
Meson-nucleon vertex corrections to the vacuum polarization in the cutoff field theory and tensor coupling
Hiroaki Kouno, Kazuharu Koide, Nobuo Noda +5
At zero-density, meson-nucleon vertex corrections to vacuum polarization are studied in the model with the cutoff. It is shown that the properties of the vertex corrections t…
