Fermion decoupling and the Axial Anomaly on the Lattice

arXiv:hep-lat/9909058 · doi:10.1016/S0920-5632(00)91849-8

Abstract

In the axial Ward identity of lattice QED we show that in the limit of infinite fermion mass m the pseudoscalar density term exactly cancels the Adler-Bell-Jackiw anomaly. Using this result we calculate the U(1) axial anomaly in a non-abelian gauge theory.
