Chiral anomaly and unambiguous rational terms
Jifeng Yang, Guang-jiong Ni
Abstract
Through more detailed calculations on QED1+1 and QED3+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.
