TL;DR

This paper extends the renormalizable Wess-Zumino model to all orders on bosonic-fermionic noncommutative superspace, simplifying the action and demonstrating its renormalizability through systematic construction of operators and parameters.

Contribution

It introduces a simplified, manifest 1/2 supersymmetric form of the BFNC Wess-Zumino action and proves its renormalizability to all orders in noncommutative parameters.

Findings

The action can be extended to all orders of noncommutative parameters.

The simplified form maintains manifest 1/2 supersymmetry.

The model is proven renormalizable to all orders.

Abstract

In our previous paper we construct a renormalizable Wess-Zumino action on BFNC superspace at the second order approximation of noncommutative parameters. The action contains about 200 terms which are necessary for renormalization. By removing chiral covariant derivatives and chiral coordinates we found that the BFNC Wess-Zumino action can be transformed to a simpler form which have manifest 1/2 supersymmetry. Based on this discovery, we can extend the BFNC Wess-Zumino action to the all order of noncommutative parameters. At first we introduce global symmetries, then obtain divergent operators in the effective action by using dimensional analysis, the next step is to construct all possible BFNC parameters, at the end we combine the BFNC parameters with the divergent operators. We present the explicit action up to the fourth order of noncommutative parameters. Because the action contain all possible divergent operators, it is renormalizable to all order in perturbative theory.
