A Stueckelberg extension of the MSSM with only one abelian vector and onechiral superfield as an alternative to an abelian extension with Higgs scalarsis presented. The bosonic sector contains a new gauge boson Z' which is a sharpresonance, and a new CP-even scalar, which combines with the MSSM Higgs bosonsto produce three neutral CP-even massive states. The neutral fermionic sectorhas two additional fermions which mix with the four MSSM neutralinos to producean extended 6x6 neutralino mass matrix. For the case when the LSP is composedmostly of the Stueckelberg fermions, the LSP of the MSSM will be unstable,which leads to exotic decays of sparticles with many leptons in final states.Prospects for supersymmetry searches and for dark matter are discussed.Comment: 10 page
