Effective Potential of Nambu–Jona-Lasinio Model in Differential Regularization
The method of differential regularization is applied to calculate explicitly the one-loop effective potential of a bosonized Nambu–Jona-Lasinio model consisting of scalar and pseudoscalar fields. The regularization scheme independent relation for the σ mass sum rule is obtained. This method can be readily applied to extended NJL models with gauge fields. PACS:11.10.Gh, 11.15.Bt, 12.50.Lr

We study the K → 2π decays using the U L (3) × U R (3) version of the Nambu-Jona-Lasinio model with the effective ∆S = 1 nonleptonic weak interaction. The ∆I = 3 2 amplitude is in reasonable agreement with experimental data. On the other hand, the calculated ∆I = 1 2 amplitudes strongly depend on the mass of the low-lying scalar-isoscalar σ meson, and therefore give a strong constraint on the p...

The transition amplitude for πK scattering is evaluated within the SU(3) Nambu–Jona-Lasinio model. Ordering terms according to the expansion in 1/Nc leads to a box-like diagram, t channel diagrams that admit scalar isoscalar (σ, σ′) exchanges, and a u channel exchange of a scalar isodoublet σK that has quantum numbers corresponding to the K∗ 0 (1430). Both the Pauli-Villars and O(3) regularizat...
متن کاملNonet meson properties in Nambu–Jona-Lasinio model with dimensional versus cutoff regularization
Nambu–Jona-Lasinio (NJL) model with Kobayashi-Maskawa-’t Hooft (KMT) term is one of low energy effective theory of QCD which includes the UA(1) anomaly. We investigate nonet meson properties in this model with three flavors of quarks. We employ two type of regularizations the dimensional and sharp cutoff ones. The model parameters are fixed phenomenologically for each regularization. Evaluating...
متن کاملChiral Anomaly and Nucleon Properties in the Nambu–jona-lasinio Model with Vector Mesons
We consider the extended SU(3) Nambu and Jona-Lasinio model with explicit vector couplings in the presence of external fields. We study the chiral anomaly in this model and its implications on the properties of the nucleon described as a chiral soliton of three valence quarks bounded in mesonic background fields. For the model to reproduce the QCD anomaly it is necessary to subtract suitable lo...
