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…

Fermions on lattice and chiral invariance
H. Banerjee, Asit K. De
A model for lattice fermion is proposed which is, (i) free from doublers, (ii) hermitian, and (iii) chirally invariant. The price paid is the loss of hypercubic and reflection symm…

Resolution of the strong CP and U(1) problems
H. Banerjee
Definition of the determinant of Euclidean Dirac operator in the nontrivial sector of gauge fields suffers from an inherent ambiguity. The popular Osterwalder-Schrader (OS) recipe…
