Effective meson masses, effective meson-nucleon couplings and neutron star radii
Kunito Tuchitani, Yasushi Horinouchi, Taihei Iwamitsu +5
Using the generalized mean field theory, we have studied the relation among the effective meson masses, the effective meson-nucleon couplings and the equation of state (EOS) in asy…

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…
Antiproton Production in p+d Reaction at Subthreshold Energies
A. Hasegawa, Y. Iwasaki, K. Sakamoto +3
An enhancement of antiprotons produced in p+d reaction in comparison with ones in p+p elementary reaction is investigated. In the neighborhood of subthreshold energy the enhancemen…

Liang-gang Liu, Xiang-qian Luo, Qi-fa Zhou +2
The particle-hole and Delta -hole excitations are well-known elementary excitation modes for the pion propagator in nuclear matter. But, the excitation also involves antiparticles,…
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
