Anomalous sector of chiral Lagrangian is calculated in a gauge invariant,
nonlocal, dynamical quark model. The Wess-Zumino term is proved coming from two
kinds of sources, one is independent on and another dependent on dynamical
quark self energy
Σ(k2). p6 and more higher order anomalous sectors come only from
Σ(k2) dependent source. After some cancellation, standard
Wess-Zumino action is obtained.Comment: 10 page
