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…
