On the ambiguities in the effective action in Lorentz-violating gravity
M. Gomes, T. Mariz, J. R. Nascimento +3
We investigate the occurrence of ambiguities for Lorentz-violating gravitational Chern-Simons term. It turns out that this term is accompanied by a coefficient depending on an unde…
On duality of the noncommutative Maxwell-Chern-Simons theory
M. Gomes, J. R. Nascimento, A. Yu. Petrov +2
We study the possibility of establishing the dual equivalence between the noncommutative Maxwell-Chern-Simons theory and the noncommutative self-dual theory. It turns to be that wh…
Perturbative finiteness of the three-dimensional Susy QED to all orders
A. F. Ferrari, M. Gomes, A. C. Lehum +2
Within the superfield formalism, we study the ultraviolet properties of the three-dimensional supersymmetric quantum electrodynamics. The theory is shown to be finite at all loops…
Spontaneous gauge symmetry breaking in a supersymmetric Chern-Simons model
A. C. Lehum, A. F. Ferrari, M. Gomes +1
This works presents a perturbative analysis of the supersymmetric Chern-Simons model in three spacetime dimensions coupled to a Higgs field, using the superfield formalism. We stud…
Dynamical Lorentz and CPT symmetry breaking in a 4D four-fermion model
M. Gomes, T. Mariz, J. R. Nascimento +1
In a 4D chiral Thirring model we analyse the possibility that radiative corrections may produce spontaneous breaking of Lorentz and CPT symmetry. By studying the effective potentia…
On the finiteness of the noncommutative supersymmetric Maxwell-Chern-Simons theory
A. F. Ferrari, M. Gomes, J. R. Nascimento +3
Within the superfield approach, we prove the absence of UV/IR mixing in the three-dimensional noncommutative supersymmetric Maxwell-Chern-Simons theory at any loop order and demons…
