No radiative generation of Chern-Simons-like term in Lorentz-violating QED: dealing with IR divergences

O. M. Del Cima, D. H. T. Franco, O. Piguet

The issue intensively claimed in the literature on the generation of a CPT-odd and Lorentz violating Chern-Simons-like term by radiative corrections owing to a CPT violating intera…
