Abstract : Universiti Pendidikan Sultan Idris

In this project, we review the global (or rigid) supersymmetry algebra (N= 1 and N=2), Lagrangian supersymmetry fields and its simple supersymmetry transformations. Then we also discuss the local supersymmetry or supergravity briefly including field spin-3/2. We study spontaneous N=2->N=1 supersymmetry breaking in supergravity within consideration of Minkowski background (flat space without cosmological constant). We develop new representation of dual supersymmetry from Ferrara Nieuwenhuizen N=1 massive spin-3/2 supersymmetry which has multiplet (3/2, 1, 1, 1/2) by means Poincare duality of massive vector fields. We couple the supergravity coupling upon each of the supersymmetry representations. Non-linear realization is responsible for partial supersymmetry breaking was studied. We used UnHiggs technique upon each representation and find a new N=2 supergravity for Minkowski background appear.
