- Description
- The Schwinger model, when quantized in a gauge non-invariant way exhibits a dependence on a parameter a (the Jackiw-Rajaraman parameter) in a way which is analogous to the case involving chiral fermions (the chiral Schwinger model). For all values of <math> a\neq 1\,\!</math>, there are divergences in the fermionic Green's functions. We propose a regularization of the generating functional <math>Z[\eta,\overline\eta,J]\,\!</math> and we use it to renormalize the theory to one loop level, in a semi-perturbative sense. At the end of the renormalization procedure we find an implicit dependence of a on the renormalization scale <math>\mu\,\!</math>.
