Chiral anomaly and unambiguous rational terms

Abstract

Through more detailed calculations on QED${}_{1+1}$ and QED${}_{3+1}$ emplying a new treatment of Feynman Amplitudes, we attribute the regularization independent and hence definite origin of chiral anomaly in perturbation theory to an unambiguous term which is a rational function in momentum space. Some relevant remarks are presented.
