Chiral Anomalies In Field Theories
H. Banerjee
The role of the contribution from the fermion mass term in the axial vector Ward identity in generating the U(1) axial anomaly, both local and global, is elucidated. Gauge invarian…

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…
