One-loop renormalisation of N=1/2 supersymmetric gauge theory

TL;DR

This paper demonstrates that N=1/2 supersymmetric gauge theory is renormalisable at one loop, but requires a non-trivial restoration of gauge invariance to achieve this.

Contribution

It provides a proof of one-loop renormalisability for N=1/2 supersymmetric gauge theory with a novel gauge invariance restoration method.

Findings

N=1/2 supersymmetric gauge theory is renormalisable at one loop

Gauge invariance must be restored non-trivially for renormalisability

The approach clarifies the structure of divergences in the theory

Abstract

We show that N=1/2 supersymmetric gauge theory is renormalisable at one loop, but only after gauge invariance is restored in a non-trivial fashion.
