Chiral anomaly and CPT invariance in an implicit momentum space regularization framework - art. no. 046013

This is the second in a series of two contributions in which we set out to establish a novel momentum space framework to treat field-theoretical infin ities in perturbative calculations when parity-violating objects occur. Sin ce no analytic continuation on the space-time dimension is effected, this f ramework can be particularly useful to treat dimension-specific theories. M oreover, arbitrary local terms stemming from the underlying. infinities of the model can be properly parametrized. We (re)analyze the indeterminacy of the radiatively generated CPT violating Chern-Simons term within an extend ed version of QED(4) and calculate the Adler-Bardeen-Bell-Jackiw triangle a nomaly to show that our framework is consistent and general enough to handl e the subtleties involved when a radiative correction is finite.
