On perturbative aspects of a nonminimal Lorentz-violating QED with CPT-odd dimension-6 terms
T. Mariz, M. Melo, J. R. Nascimento +1
In this paper, we investigate the first-order one-loop quantum corrections generated by all possible nonminimal dimension-6 additive CPT-odd Lorentz-violating (LV) terms to analyze…
Two-loop corrections to the Carroll-Field-Jackiw term in a CPT-odd Lorentz-violating scalar QED
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov
In this study, we systematically calculate one-loop corrections to the Lorentz-violating vertices within the framework of CPT-odd Quantum Electrodynamics, encompassing scalar and p…
On perturbative aspects of a nonminimal Lorentz-violating QED with CPT-even dimension-5 terms
T. Mariz, M. Melo, J. R. Nascimento +1
In this paper, we explicitly calculate the lower CPT-even one-loop quantum corrections in nonminimal Lorentz-violating spinor QED with all possible CPT-even dimension-5 operators.…
On metric-affine bumblebee model coupled to scalar matter
J. R. Nascimento, Gonzalo J. Olmo, A. Yu. Petrov +1
We consider the coupling of the metric-affine bumblebee gravity model to scalar matter and calculate the lower-order contributions to two-point functions of bumblebee and scalar fi…
Lorentz-breaking Rarita-Schwinger model
M. Gomes, T. Mariz, J. R. Nascimento +1
In this paper, we formulate the Lorentz-breaking extension for the spin-3/2 field theory and couple it to the Abelian gauge field in a Lorentz violating (LV) manner. Next, we calcu…
Lorentz symmetry breaking and supersymmetry
J. R. Nascimento, A. Yu. Petrov
We discuss three manners to implement Lorentz symmetry breaking in a superfield theory formulated within the superfield formalism, that is, deformation of the supersymmetry algebra…
