| Abstract |
The Nambu-Jona-Lasinio model with a Kobayashi-Maskawa-'t Hooft term is one low energy effective theory of QCD which includes the U_A(1) anomaly. We investigate nonet meson properties in this model with three flavors of quarks. We employ two types of regularizations, the dimensional and sharp cutoff ones. The model parameters are fixed phenomenologically for each regularization. Evaluating the kaon decay constant, the η meson mass and the topological susceptibility, we show the regularization dependence of the results and discuss the applicability of the Nambu-Jona-Lasinio model.
