| dc.description | I consider global transformations of a Dirac fermion field, that are generated by the generators of Poincar'e transformations, but with a γ_5 appended. Such chiral translations and chiral Lorentz transformations are usually not symmetries of the Lagrangian, but naively they are symmetries of the fermionic measure. However, by using proper time regularization in Minkowski space, I find that they in general give rise to a nontrivial Jacobian. In this sense they have "anomalies". I calculate these anomalies in a theory of a massive fermion coupled to an external Abelian vector field. My motivation for considering chiral Poincar'e transformations is the possibility that they are relevant to bosonization in four dimensions. | |
