We review the history of non-renormalisation theorems in global supersymmetry, as well as their importance in all attempts to apply supersymmetry to the real world.

The partial breaking of supersymmetry in flat space can be accomplished using any one of three dual representations for the massive N = 1 spin-3/2 multiplet. Each of the representations can be “unHiggsed”, which gives rise to a set of dual N = 2 supergravities and supersymmetry algebras.

In this paper, the study of restoration of Supersymmetry, broken at tree level, has been undertaken. In the present model we have lucratively applied the method of back propagation based on gradient descent along the error surface to restore the supersymmetry against arbitrary tiny quantum corrections in the form of small thermal agitations. Back propagation method brings the potential stabilit...

A simple hadronic axion model is proposed in the framework of gaugemediated supersymmetry breaking. Dynamics of Peccei-Quinn symmetry breaking is governed by supersymmetry breaking effects and the Peccei-Quinn breaking scale fPQ is inversely proportional to the gravitino mass. The gravitino mass range which corresponds to the axion window fPQ ≃ 109 GeV – 1013 GeV lies in the region predicted by...

Abstract. The lattice Wess-Zumino model written in terms of the Ginsparg-Wilson relation is invariant under a generalized supersymmetry transformation which is determined by an iterative procedure in the coupling constant. By studying the associated Ward-Takahashi identity up to order g we show that this lattice supersymmetry automatically leads to restoration of continuum supersymmetry without...
