“…Again, as in the previous case, we will have contributions involving both second and higher derivatives, and they are divergent. The explicit result, as well as some consequences derived from it, have been studied in [61].…”

“…As a first example, we consider the vertex proportional to H μναβ F , which corresponds to T μ = − 1 2 H αβλμ σ αβ ∂ λ . In this case, the calculations will be analogous to [61], with the only difference being the presence of the γ 5 factor which results in the mapping H αβλμ → 1 2 H σρ αβ σρλμ . Therefore, we can write (54) which yields, for the divergent part,…”

Radiative corrections and Lorentz violation

2020

Radiative corrections in Lorentz violating (LV) models have already received a lot of attention in the literature in recent years, with many instances where a LV operator in one sector of the Standard Model Extension (SME) generates, via loop corrections, one of the LV coefficients in the photon sector, which is probably the most understood and well constrained part of the SME. In many of these works, however, the now standard notation of the SME is not used, which can obscure the comparison of different results, and their possible phenomenological relevance. In this work, we fill this gap, trying to build up a more general perspective on the topic, bringing many of the results to the SME conventional notation and commenting on their possible phenomenological relevance. We uncover one example where a result already presented in the literature can be used to place a stronger bound on the temporal component of the b μ coefficient of the fermion sector of the SME.

“…The study of the nonminimal operators was started with the development of the nonminimal versions of the SME for both the fermion [38] and the photon sector [39]. We also mention investigations which concern the point-charge self-energy [40], the study of radiative corrections [41][42][43][44][45], the search for Lorentz violation effects through boundary conditions [46].…”

This paper is devoted to the study of interactions between stationary electromagnetic sources for the minimal and nonminimal CPT-odd photon sector of the Standard Model Extension (SME), where we search mainly for physical phenomena not present in the Maxwell electrodynamics.First we consider the minimal CPT-odd sector, where the Lorentz violation is caused by the Carroll-Field-Jackiw (CFJ) term, namely ∼ µναβ (k AF ) µ A ν F αβ , and we treat the Lorentz breaking parameter (k AF ) µ perturbatively up to second order. We consider effects due to the presence of point-like charges, Dirac strings and point-like dipoles. In special, we calculate the electromagnetic field produced outside the string and investigate the so called Aharonov-Bohm bound states in Lorentz violation context. After, we consider a model where the Lorentz violation is generated by the higher-derivative version of the CFJ model, namely ∼ µναβ V µ A ν F αβ , which is a dimension five term of the CPT-odd sector of the nonminimal SME. For this higher-derivative model, we obtain effects up to second order in V µ related to the presence of point-like charges and a steady current line. We use overestimated constrains for the Lorentz violation parameters in order to investigate the physical relevance of some results found in atomic systems. We also make an overestimate for the background vectors using experimental data from the atomic electric field.

“…Nevertheless, it should be noted that in principle, these terms can arise even if the magnetic coupling is not used, see [12,14]. Further, perturbative impacts of the CPT-even nonminimal coupling κ αβμν ψσ μν F αβ ψ were studied in [17,18].…”

On perturbative aspects of a nonminimal Lorentz-violating QED with CPT-odd dimension-5 terms

et al. 2021

We consider the Lorentz-violating extended QED involving all nonminimal dimension-5 additive CPT-odd terms. For this theory, we investigate the generation of the Carroll–Field–Jackiw (CFJ) term and its higher-derivative counterparts of the first order in any of these nonminimal couplings. The CFJ term is demonstrated to vanish in the dimensional regularization scheme. We also study the question of higher-derivative divergent contributions and demonstrate that they can be eliminated by considering a given proportionality between the coefficients.
