Fermion decoupling and the axial anomaly on the lattice
H. Banerjee, Asit K. De
By an explicit calculation of the continuum limit of the triangle graph amplitude in lattice QED we show that in the axial Ward identity the ABJ anomaly exactly cancels the pseudos…

Lattice Fermions and the Chiral Anomaly
H. Banerjee, Asit K. De
We show in the Wilson model that the contribution of the regular mass term to the four-divergence of the axial vector current in weak coupling perturbation theory is not zero in th…
