Maxwell electrodynamics modified by CPT-even and Lorentz-violating dimension-6 higher-derivative terms
Rodolfo Casana, Manoel M. Ferreira, Letícia Lisboa-Santos +2
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…
Lorentz-violating nonminimal coupling contributions in mesonic hydrogen atoms and generation of photon higher-order derivative terms
R. Casana, J. S. Rodrigues, F. E. P. dos Santos
We have studied the contributions of Lorentz-violating CPT-odd and CPT-even nonminimal couplings to the energy spectrum of the mesonic hydrogen and the higher-order radiative corre…
Gupta-Bleuler's quantization of a parity-odd CPT-even electrodynamics of the standard model extension
R. Casana, M. M. Ferreira, F. E. P. dos Santos
{Following a successfully quantization scheme previously }{{% developed {\ in Ref. \cite{GUPTAEVEN} for a}} parity-even {gauge sector} {of the SME, we}} have established the Gupta-…
Gupta--Bleuler's quantization of the anisotropic parity-even and CPT-even electrodynamics of standard model extension
R. Casana, M. M. Ferreira, F. E. P. dos Santos
We have established the Gupta-Bleuler quantization of the photon belonging to the anisotropic parity-even sector of the CPT-even and Lorentz-violating nonbirefringent electrodynami…
A CPT-even Lorentz-violating nonminimal coupling between fermions and photons
R. Casana, M. M. Ferreira, E. Passos F. E. P. Dos Santos +1
We propose a CPT-even and Lorentz-violating dimension-five nonminimal coupling between fermionic and gauge fields, involving the CPT-even and Lorentz-violating gauge tensor of the…
Radiative generation of the CPT-even gauge term of the SME from a dimension-five nonminimal coupling term
R. Casana, M. M. Ferreira, R. V. Maluf +1
In this letter we show for the first time that the usual CPT-even gauge term of the standard model extension (SME) can be radiatively generated, in a gauge invariant level, in the…
