On the finiteness of noncommutative supersymmetric QED in the covariant superfield formulation
A. F. Ferrari, H. O. Girotti, M. Gomes +3
The three-dimensional noncommutative supersymmetric QED is investigated within the superfield approach. We prove the absence of UV/IR mixing in the theory at any loop order and dem…
Superfield covariant analysis of the divergence structure of noncommutative supersymmetric QED
A. F. Ferrari, H. O. Girotti, M. Gomes +4
Commutative supersymmetric Yang-Mills is known to be renormalizable for , while finite for . However, in the noncommutative version of the model (NCS…
(2+1)D Noncommutative CP Model
E. A. Asano, M. Gomes, A. G. Rodrigues +1
We investigate possible extensions of the (2+1) dimensional model to the noncommutative space. Up to the leading nontrivial order of 1/N, we prove that the model restric…
Dynamical Breakdown of Symmetry in a (2+1) Dimensional Model Containing the Chern-Simons Field
Alex G. Dias, M. Gomes, A. J. da Silva
We study the vacuum stability of a model of massless scalar and fermionic fields minimally coupled to a Chern-Simons field. The classical Lagrangian only involves dimensionless par…
Radiative corrections to the Chern-Simons term at finite temperature in the noncommutative Chern-Simons-Higgs model
L. C. T. de Brito, M. Gomes, Silvana Perez +1
By analyzing the odd parity part of the gauge field two and three point vertex functions, the one-loop radiative correction to the Chern-Simons coefficient is computed in noncommut…
