NON-ANOMALOUS GENERALIZED CHIRAL SCHWINGER MODEL

Recently, Basseto and Griguolo(1) did a perturbative quantization of w hat they called a generalized chiral Schwinger model. As a consequence of the kind of quantization adopted, some gauge-dependent masses rais ed in the model. On the other hand, we discussed the possibility of in troducing a generalized Wess-Zumino term,(2) where such gauge-dependen t masses did appear. Here we intend to show that one can construct a n on-anomalous version of a model which include that presented by Basset o and Griguolo as a particular case, by adding to it a generalized Wes s-Zumino term, as proposed in Ref. 2. So we conclude that it is possib le to construct a gauge-invariant extension of the model quoted in Ref . 1, and this can be done through a Wess-Zumino term of the type propo sed in Ref. 2.
