ANOMALY THROUGH GAUGE-INVARIANT REGULARIZATION WITH INFINITE NUMBER OF PAULI-VILLARS FIELDS

Abstract
Abelian anomaly is examined by means of the recently proposed gauge-invariant regularization for SO(10) chiral gauge theory and its generalization for a theory of arbitrary gauge group with anomaly-free chiral fermion contents. For both cases it is shown that the anomaly with correct normalization can be obtained in a gauge-invariant form without any counterterms.
