Extending the Euler-Heisenberg action to include effects of local Lorentz-symmetry violating backgrounds
Wagno Cesar e Silva, João Paulo S. Melo, José A. Helayël-Neto
This work sets out to compute the corrections to the Euler-Heisenberg effective action that arise from spacetime-dependent background anisotropies that violate Lorentz symmetry. To…
Experimental signatures of Kalb-Ramond-like particles
P. C. Malta, J. P. S. Melo, C. A. D. Zarro
We analyse phenomenological signatures of Kalb-Ramond-like particles, described by an antisymmetric rank-2 tensor, when coupled to fermionic matter. The latter is modelled by a ten…
Re-assessing special aspects of Dirac fermions in presence of Lorentz-symmetry violation
João Paulo S. Melo, José A. Helayël-Neto
This paper focuses on additional inspections concerning the fermionic sector of the Standard Model Extension (SME). In this context, our main effort in this contribution is to inve…
Loop Quantum Gravity effects on electromagnetic properties of charged leptons
João Paulo S. Melo, Mario J. Neves, Jefferson M. A. Paixão +1
The efforts in this contribution consist in reassessing a modified Dirac equation that incorporates a -Lorentz-symmetry violating (LSV) term induced as a Loop Quantum Grav…
SUSY QED with Lorentz-asymmetric fermionic matter and a glance at the electron's EDM
João Paulo S. Melo, Wagno Cesar e Silva, José A. Helayël-Neto
This contribution sets out to pursue the investigation of a supersymmetric electrodynamics model with Lorentz-symmetry violation (LSV) manifested by a space-time unbalance in the p…
