SUMMARY:

The Schwinger model, i.e. quantum electrodynamics (QED) in two dimensions with massless fermions, is the simplest model for fermionic fields that implements several features also observed in other more realistic 4D gauge models. It is also an interesting feature of the model that, being two-dimensional, vector and axial fermionic currents are not independent of each other. Thus, the chiral Schwinger model polarization model is related to the same possible Schwinger model tree. Finally, the solution of the action in divergences in the fits within the model, Schwinger model is finite, in other words, is free of divergences. Despite the results when the regularization schemes are used, being recognized, therefore, as an indeterminate quantity, we intend to investigate the same phenomenon (fin ambiguities in the same phenomenon) Schwinger), from the perspective of the Spectral Model of quarks.
