General CPT-even dimension-five nonminimal couplings between fermions and photons yielding EDM and MDM


Abstract in English

In this letter, we examine a new class of CPT-even nonminimal interactions, between fermions and photons, deprived of higher order derivatives, that yields electric dipole moment (EDM) and magnetic dipole moment (MDM) in the context of the Dirac equation. The couplings are dimension-five CPT-even and Lorentz-violating nonminimal structures, composed of a rank-2 tensor, $T_{mu u}$, the electromagnetic tensor, and gamma matrices, being addressed in its axial and non-axial Hermiti
