Zeta function regularization, anomaly and complex mass term

High Energy Physics - Theory 2015-05-27 v2

Abstract

If the zeta function regularization is used and a complex mass term considered for fermions, the phase does not appear in the fermion determinant. This is not a drawback of the regularization, which can recognize the phase through source terms, as demonstrated by the anomaly equation which is explicitly derived here for a complex mass term.
