The UL(3) × UR(3) Extended Nambu--Jona-Lasinio Model in Differential Regularization
Yaw-Hwang Chen, Su-Long Nyeo, Yeou-Wei Yang
Abstract
We employ the method of differential regularization to calculate explicitly the one-loop effective action of a bosonized UL(3)× UR(3) extended Nambu--Jona-Lasinio model consisting of scalar, pseudoscalar, vector and axial vector fields.
