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…
Anomaly cancellation in three-dimensional noncommutative gauge theories
M. Gomes, T. Mariz, J. R. Nascimento +3
The anomaly found by Callan and Harvey is shown to be cancelled in a three-dimensional noncommutative gauge theory coupled to a fermion with a mass function depending on one spatia…
On the induction of the four-dimensional Lorentz-breaking non-Abelian Chern-Simons action
M. Gomes, J. R. Nascimento, E. Passos +2
A four-dimensional Lorentz-breaking non-Abelian Chern-Simons like action is generated as a one-loop perturbative correction via an appropriate Lorentz-breaking coupling of the non-…
