Soft supersymmetry breaking and the Supersymmetric Standard Model

We recall how the idea of Softly Broken Supersymmetry led to the constructi on of the Supersymmetric Standard Model in 1981. Its first prediction, the supersymmetric unification of gauge couplings, was conclusively verified by the LEP and SLC experiments 10 years later. Its other predictions include: the existence of superparticles at the electroweak scale; a stable lightes t superparticle (LSP) with a mass of similar to 100 GeV, anticipated to be a neutral electroweak gaugino; the universality of scalar and gaugino masse s at the unification scale. The original motivation for the model, solving the hierarchy problem, indicates that the superparticles should be discover ed at the LHC or the TeVatron.
