Brout-Englert-Higgs boson as spin-0 partner of the Z in the supersymmetric standard model

Supersymmetric extensions of the standard model lead to gauge/Brout-Englert-Higgs (BEH) unification by providing spin-0 bosons as extra states for spin-1 gauge bosons within massive gauge multiplets. They may be described by the spin-0 components of massive gauge superfields (instead of chiral superfields as usual). In particular, the 125 GeV/c super(2) boson observed at CERN, considered as a BEH boson associated with electroweak breaking and mass generation, may also be interpreted, up to a mixing angle induced by supersymmetry breaking, as the spin-0 partner of the Z under two supersymmetry transformations, i.e., as a Z that would be deprived of its spin.
