Chiral anomalies and Poincare invariance
Jan B. Thomassen
I study variations of the fermionic determinant for a nonabelian Dirac fermion with external vector and axial vector sources. I consider different regularizations, leading to diffe…
Chiral Poincare transformations and their anomalies
Jan B. Thomassen
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…
Jacobians of chiral transformations and two-dimensional bosonization
Jan B. Thomassen
We formulate a complete path integral bosonization procedure for any fermionic theory in two dimensions. The method works equally well for massive and massless fermions, and is a g…
Path Integral Bosonization of the Massive Thirring Model
Jan B. Thomassen
There is a conceptual error in the main argument of this paper (essentially a regularization scheme is changed in the middle of a calculation), and therefore it is withdrawn. Inter…
