Gauge (in)dependence and UV/IR mixing
M. Attems, D. N. Blaschke, S. Hohenegger +2
The gauge independence in connection with the UV/IR-mixing is discussed with the help of the non-commutative U(1)-gauge field model proposed by A. A. Slavnov with two different gau…
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…
Deformed QED via Seiberg-Witten Map
A. A. Bichl, J. M. Grimstrup, L. Popp +2
With the help of the Seiberg-Witten map for photons and fermions we define a theta-deformed QED at the classical level. Two possibilities of gauge-fixing are discussed. A possible…
The energy-momentum tensor on noncommutative spaces - some pedagogical comments
A. Gerhold, J. Grimstrup, H. Grosse +3
We present the discussion of the energy-momentum tensor of the scalar - theory on a noncommutative space. The Noether procedure is performed at the operator level. Additionall…
A comment on the 4D antisymmetric tensor field model
J. Rant, M. Schweda, H. Zerrouki
We show the existence of a renormalizable local supersymmetry for the gauge fixed action of the four dimensional antisymmetric tensor field model in a curved background quantized i…
The Yang--Mills gauge field theory in the context of a generalized BRST--formalism including translations
O. Moritsch, M. Schweda, T. Sommer
We discuss the algebraic renormalization of the Yang--Mills gauge field theory in the presence of translations. Due to the translations the algebra between Sorella's $\d$--operator…
