Fermion decoupling and the Axial Anomaly on the Lattice
H. BanerjeeAsit K. De
文献摘要
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.
