The schwinger model and its axial anomaly

Webbthe theory’s violation of chiral symmetry and its chiral anomaly. Here we will see that the chiral anomaly leads to the mass generation of the scalar field. The solution of the Schwinger model will be done through bosonization in order to illustrate a non-perturbative method. Actually, the physics of the model can be extracted via perturbative WebbN. S.
