On the consistency of the three-dimensional noncommutative supersymmetric Yang-Mlls theory
(2004) [Artigo de periódico]We study the one-loop quantum corrections to the U(N) noncommutative supersymmetric Yang–Mills theory in three spacetime dimensions (NCSYM3). We show that the cancellation of the dangerous UV/IR infrared divergences only ... -
On the finiteness of noncommutative supersymmetric QED/sub 3/ in the covariant superfield formulation
(2003) [Artigo de periódico]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 demonstrate its one-loop finiteness. -
Superfield covariant analysis of the divergence structure of noncommutative supersymmetric QED/sub 4/
(2004) [Artigo de periódico]Commutative supersymmetric Yang-Mills is known to be renormalizable for N51,2, while finite for N 54. However, in the noncommutative version of the model (NCSQED4) the UV-IR mechanism gives rise to infrared divergences ... -
Towards a consistent noncommutative supersymmetric Yang-Mills theory : superfield covariant analysis
(2004) [Artigo de periódico]Commutative four dimensional supersymmetric Yang-Mills (SYM) theory is known to be renormalizable for N=1,2, and finite for N=4. However, in the noncommutative version of the model the UV/IR mechanism gives rise to infrared ...
