Repercussions of dimension five nonminimal couplings in the electroweak model

We propose two possibilities of CPT-odd, dimension five and Lorentz-violating (LV) nonminimal couplings in the Electroweak model. These gauge-invariant terms couple a fixed LV 4-vector to the

Fermion Scattering in a CPT-Even Lorentz Violation Quantum Electrodynamics

TLDR
This work reassess two known processes of Quantum Electrodynamics involving electrons and muons with modified photon propagator and associated cross sections for unpolarized scatterings, revealing the usual energy dependence and Lorentz-violating contributions that induce space anisotropy.

Testing Lorentz and CPT invariance with ultracold neutrons

In this paper we investigate, within the standard model extension framework, the influence of Lorentz- and CPT-violating terms on gravitational quantum states of ultracold neutrons. Using a

Bounds on Lorentz-violating Yukawa couplings via lepton electromagnetic moments

The effective-Lagrangian description of Lorentz-invariance violation provided by the so-called Standard-Model Extension covers all the sectors of the Standard Model, allowing for model-independent

Lorentz-violating contributions to the nuclear Schiff moment and nuclear EDM.

In the context of an atom endowed with nuclear EDM, we consider the effects on the Schiff moment of $CPT$-even Lorentz-violating (LV) terms that modify the Coulomb potential. First, we study the

Maxwell electrodynamics modified by CPT -even and Lorentz-violating dimension-6 higher-derivative terms

In this paper, we investigate an electrodynamics in which the physical modes are coupled to a Lorentz-violating (LV) background by means of a higher-derivative term. We analyze the modes associated

One-loop structure of the photon propagator in the standard model extension

We study radiative corrections on the photon propagator from the electroweak sector of the minimal Lorentz- and $CPT$-violating Standard Model Extension. We derive the most general Lorentz-violating

Constraining CPT-even and Lorentz-violating nonminimal couplings with the electron magnetic and electric dipole moments

We analyse some dimension-five CPT-even and Lorentz-violating nonminimal couplings between fermionic and gauge fields in the context of the Dirac equation. After evaluating the nonrelativistic

New $CPT$-even and Lorentz-violating nonminimal coupling in the Dirac equation

In this work, we propose a CPT-even and Lorentz-violating dimension-five nonminimal coupling between fermionic and gauge fields, involving the CTP-even and Lorentz-violating gauge tensor of the SME.

QED with minimal and nonminimal couplings: on the quantum generation of Lorentz-violating terms in the pure photon sector

We consider an effective model formed by usual QED (minimal coupling) with the addition of a nonminimal Lorentz-violating interaction (proportional to a fixed 4-vector b?) which may radiatively

Magnetic moment generation from non-minimal couplings in a scenario with Lorentz-symmetry violation

AbstractThis paper deals with situations that illustrate how the violation of Lorentz symmetry in the gauge sector may contribute to magnetic moment generation of massive neutral particles with spin-

QED with chiral nonminimal coupling: aspects of the Lorentz-violating quantum corrections

An effective model for QED with the addition of a nonminimal coupling with a chiral character is investigated. This term, which is proportional to a fixed 4-vector bμ, violates Lorentz symmetry and

Electromagnetism with dimension-five operators

We derive, in curved spacetime, the most general Lorentz-violating electromagnetic Lagrangian containing dimension-five operators with one more derivative than the Maxwell term in the hypothesis that

Gauge invariance and the CPT and Lorentz violating induced Chern–Simons-like term in extended QED

The radiative induction of the CPT and Lorentz violating Chern–Simons (CS) term is reassessed. The massless and massive models are studied. Special attention is given to the preservation of gauge

Generation of axionlike couplings via quantum corrections in a Lorentz-violating background

Light pseudoscalars, or axion like particles (ALPs), are much studied due to their potential relevance to the fields of particle physics, astrophysics and cosmology. The most relevant coupling of
