On perturbative aspects of a nonminimal Lorentz-violating QED with CPT-odd dimension-6 terms

Abstract

In this paper, we investigate the first-order one-loop quantum corrections generated by all possible nonminimal dimension-6 additive CPT-odd Lorentz-violating (LV) terms to analyze the radiative induction of the Carroll-Field-Jackiw (CFJ)-like terms. We demonstrate that for dimension-6 operators, the resulting CFJ term can diverge for some choices of LV operators; however, in all these cases, this divergence is eliminated for certain relations between LV parameters.
