Yh. Chen et al., THE U-L(3)XU(R)(3) EXTENDED NAMBU-JONA-LASINIO MODEL IN DIFFERENTIAL REGULARIZATION, International journal of modern physics A, 12(13), 1997, pp. 2361-2371
We employ the method of differential regularization to calculate expli
citly the one-loop effective action of a bosonized U-L(3) x U-R(3) ext
ended Nambu-Jona-Lasinio model consisting of scalar, pseudoscalar, vec
tor and axial vector fields.
