Fermion-fermion scattering in a Rarita-Schwinger model with Yukawa-like interaction
M. C. Araújo, J. G. Lima, J. Furtado +1
In this work, we investigate the scattering of spin- fermionic particles mediated by a Yukawa-like coupling in the context of the massive Rarita-Schwinger model. The interacti…

One-loop Euler-Heisenberg action in Lorentz-violating QED revisited
R. Araújo, T. Mariz, J. R. Nascimento +1
We discuss applications of the proper-time method in a Lorentz-violating extension of QED characterized by the addition of the term proportional to the antisymmetric tensor $H_{μ΅

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…
