Carroll-Field-Jackiw term in a massless Rarita-Schwinger model
M. Gomes, J. G. Lima, T. Mariz +2
We consider the massless Rarita-Schwinger (RS) LV QED. In this theory, we introduce the gauge fixing to obtain the propagator for the RS field, and calculate the Carroll-Field-Jack…
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…
1/N Expansion for Horava-Lifshitz like four-fermion models
M. Gomes, T. Mariz, J. R. Nascimento +2
We study a class of four-fermion Gross-Neveu like models in four dimensions with critical exponents and . The models with are known to be perturbatively nonrenorma…
Attractive Forces Between Electrons in QED
H. O. Girotti, M. Gomes, J. L. deLyra +3
Vacuum polarization effects are non-perturbatively incorporated into the photon propagator to eliminate the severe infrared problems characteristic of QED. The theory is thus r…
