By supersymmetrizing the Standard Model, one arrives at a hypothesized solution to the gauge hierarchy, or big hierarchy, problem in that supersymmetry guarantees cancellation of quadratic divergences to all orders in perturbation theory. The simplest supersymmetrization of the SM leads to the Minimal Supersymmetric Standard Model or MSSM. In the MSSM, each SM particle has a partner particle known as a super-partner or sparticle. For instance, the left- and right-electron helicity components have scalar partner selectrons ~ e L and ~ e R respectively, whilst the eight colored gluons have eight colored spin-1/2 gluino superpartners. The MSSM Higgs sector must necessarily be expanded to include two rather than one doublets leading to five physical Higgs particles h, H, A and H, whilst three of the eight Higgs component fields are absorbed by the W and Z bosons to make them massive. The MSSM is actually supported by three different sets of measurements which test for the presence of virtual superpartners:
