The Energy-Momentum Tensor in Noncommutative Gauge Field Models
J. M. Grimstrup, B. Kloiböck, L. Popp +3
We discuss the different possibilities of constructing the various energy-momentum tensors for noncommutative gauge field models. We use Jackiw's method in order to get symmetric a…
Non-commutative U(1) Super-Yang-Mills Theory: Perturbative Self-Energy Corrections
A. A. Bichl, M. Ertl, A. Gerhold +6
The quantization of the non-commutative N=1, U(1) super-Yang-Mills action is performed in the superfield formalism. We calculate the one-loop corrections to the self-energy of the…
IR-Singularities in Noncommutative Perturbative Dynamics?
J. M. Grimstrup, H. Grosse, L. Popp +4
We analyse the IR-singularities that appear in a noncommutative scalar quantum field theory on . We demonstrate with the help of the quadratic one-loop effective act…
The role of the field redefinition in noncommutative Maxwell theory
I. Fruhwirth, J. M. Grimstrup, Z. Morsli +2
We discuss -deformed Maxwell theory at first order in with the help of the Seiberg-Witten (SW) map. With an appropriate field redefinition consistent with the SW-map we anal…
Noncommutative spin-1/2 representations
J. M. Grimstrup, H. Grosse, E. Kraus +3
In this letter we apply the methods of our previous paper hep-th/0108045 to noncommutative fermions. We show that the fermions form a spin-1/2 representation of the Lorentz algebra…
Noncommutative Lorentz Symmetry and the Origin of the Seiberg-Witten Map
A. A. Bichl, J. M. Grimstrup, H. Grosse +4
We show that the noncommutative Yang-Mills field forms an irreducible representation of the (undeformed) Lie algebra of rigid translations, rotations and dilatations. The noncommut…
