Abstract: (APS)
We show that our conclusions about the consistency of massive chiral electrodynamics in four dimensions were based on the use of a peculiar, although popular, expression of the chiral triangle amplitude for massless fermions, viz., a Bose-symmetric sum of Dolgov-Zakharov poles. If the Feynman triangular amplitude is instead computed by means of standard ultraviolet regulators, no decoupling of the unphysical degree of freedom occurs, thereby jeopardizing perturbative unitarity. Our present analysis raises severe doubts about the possibility of a consistent treatment of anomalous theories in a perturbative context.- quantum electrodynamics: chiral
