Light Scalar Mesons in the Improved Ladder QCD
Toru Umekawa, Kenichi Naito, Makoto Oka +1
The light scalar meson spectrum is studied using the improved ladder QCD with the UA(1) breaking Kobayashi-Maskawa-'t Hooft interaction by solving the Schwinger-Dyson and Bethe-Sal…
Vector Mesons on the Light Front
K. Naito, S. Maedan, K. Itakura
We apply the light-front quantization to the Nambu--Jona-Lasinio model with the vector interaction, and compute vector meson's mass and light-cone wavefunction in the large N limit…
U_A(1) Breaking Effects on the Light Scalar Meson Spectrum
Kenichi Naito, Makoto Oka, Makoto Takizawa +1
Effects of the U_A(1) breaking interaction on the low-lying nonet scalar mesons are studied using the extended Nambu-Jona-Lasinio model. The strength of the U_A(1) breaking interac…
Effective Potential of O(N) Linear Sigma Model at Finite Temperature
Y. Nemoto, K. Naito, M. Oka
We study the O(N) symmetric linear sigma model at finite temperature as the low-energy effective models of quantum chromodynamics(QCD) using the Cornwall-Jackiw-Tomboulis(CJT) effe…
U_A(1) Symmetry Breaking and eta, eta prime mesons in the Bethe-Salpeter Approach
K. Naito, Y. Nemoto, M. Takizawa +2
U_A(1) symmetry breaking is studied by introducing the flavor mixing interaction proposed by Kobayashi, Maskawa and 't Hooft. Combining the one gluon exchange interaction, the rain…
Renormalization Group Approach to the O(N) linear Sigma Model at Finite Temperature
T. Umekawa, K. Naito, M. Oka
The Wilsonian renormalization group (RG) method is applied to finite temperature systems for the study of non-perturbative methods in the field theory. We choose the O(N) linear si…
