Generalized Proper-Time Approach For The Case Of Broken Isospin Symmetry
Alexandre A. Osipov, Brigitte Hiller
We present a derivation of the low-energy effective meson Lagrangian of the Nambu -- Jona-Lasinio (NJL) model on the basis of Schwinger's proper-time regularization of the one-loop…

Effective Chiral Meson Lagrangian For The Extended Nambu-Jona-Lasinio Model
Alexander A. Osipov, Brigitte Hiller
We present a derivation of the low-energy effective meson Lagrangian of the extended Nambu -- Jona-Lasinio (ENJL) model. The case with linear realization of broken $SU(2)\times SU(…

One-loop fermion determinant with explicit chiral symmetry breaking
Alexander A. Osipov, Brigitte Hiller
We use a proper-time regularization to define the one-loop fermion determinant for the case in which explicit chiral symmetry breaking takes place. We show how to obtain the polyno…
