Axial and gauge anomalies in a theory with one and two-form gauge fields

Abstract

We study the problem of axial and gauge anomalies in a reducible theory involving vector and tensor gauge fields coupled in a topological way. We consider that vector and axial fermionic currents couple with the tensor field in the same topological manner as the vector gauge one. This kind of coupling leads to an anomalous axial current, contrarily to the results found in literature involving other tensor couplings, where no anomaly is obtained.

“…The term A 1 in D = 4, which corresponds to j = 0 in eq. (2.9), was used in [20] to couple fermions to Kalb-Ramond field. As shown by the authors, this coupling leads an anomalous axial current.…”
