On the consistency of the three-dimensional noncommutative supersymmetric Yang-Mills theory
A. F. Ferrari, H. O. Girotti, M. Gomes +3
We study the one-loop quantum corrections to the U(N) noncommutative supersymmetric Yang-Mills theory in three spacetime dimensions (NCSYM). We show that the cancellation of th…
Towards a consistent noncommutative supersymmetric Yang-Mills theory: superfield covariant analysis
A. F. Ferrari, H. O. Girotti, M. Gomes +4
Commutative four dimensional supersymmetric Yang-Mills (SYM) is known to be renormalizable for , and finite for . However, in the noncommutat…
Cosmological acceleration, varying couplings, and Lorentz breaking
Orfeu Bertolami, Ralf Lehnert, Robertus Potting +1
Many candidate fundamental theories contain scalar fields that can acquire spacetime-varying expectation values in a cosmological context. Such scalars typically obey Lorentz-viola…
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…
