We study two-dimensional Euclidean models involving massless Dirac spinors coupled to topologically trivial vector and axial-vector potentials in the compactifiable case as well as in the case of constant field strengths. In both cases we derive the different forms of the anomalies and, in so doing, clarify several delicate and controversial aspects involving regularization procedures, often debated in the literature.

Abstract
We study two-dimensional Euclidean models involving massless Dirac spinors coupled to topologically trivial vector and axial-vector potentials in the compactifiable case as well as in the case of constant field strengths. In both cases we derive the different forms of the anomalies and, in so doing, clarify several delicate and controversial aspects involving regularization procedures, often debated in the literature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
