Abstract:We consider noncommutative U (1) gauge theory with the additional term, involving a scalar field λ, introduced by Slavnov in order to cure the infrared problem. We show that this theory, with an appropriate space-like axial gauge-fixing, exhibits a linear vector supersymmetry similar to the one present in the 2-dimensional BF model. This vector supersymmetry implies that all loop corrections are independent of the λAA-vertex and thereby explains why Slavnov found a finite model for the same gaugefixing.
“…Furthermore, it was shown [71,72] that the Slavnov term may be identified with a topological term similar to the BF models [165,166,167,168], e.g. :…”

“…With these choices the Slavnov term, together with the gauge fixing terms, have the form of a 2-dimensional topological BF model (cf. [71] and references therein). This action is invariant under the BRST transformations…”

“…Notice that the algebra involving s, δ i ,δ i and the (x 1 , x 2 )-plane translation generator ∂ i closes on-shell (cf. [71]). (The reader not interested in the technical details of deriving the total action and related Ward identities, may proceed directly to their consequences on page 21.)…”

Abstract. The aim of this review is to present an overview over available models and approaches to non-commutative gauge theory. Our main focus thereby is on gauge models formulated on flat Groenewold-Moyal spaces and renormalizability, but we will also review other deformations and try to point out common features. This review will by no means be complete and cover all approaches, it rather reflects a highly biased selection.

“…1 In fact, there are also two other candidates on the market, but these either reduce the degrees of freedom [9,10] or break translation invariance and have difficulties with non-trivial vacuum configurations [11,12,13] (although the latter problem might be solved [14]). 2 Notice that from Eqn.…”
In this paper we discuss one-loop results for the translation invariant non-commutative gauge field model we recently introduced in ref. [1]. This model relies on the addition of some carefully chosen extra terms in the action which mix long and short scales in order to circumvent the infamous UV/IR mixing, and were motivated by the renormalizable non-commutative scalar model of Gurau et al. [2].
