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…
Scattering of spin 1/2 particles by the 2+1 dimensional noncommutative Aharonov-Bohm potential
A. F. Ferrari, M. Gomes, C. A. Stechhahn
In this work we study modifications in the Aharonov-Bohm effect for relativistic spin 1/2 particles due to the noncommutativity of spacetime in dimensions. The noncommutati…
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…
