The BE-Higgs boson as spin-0 partner of the Z, in the Supersymmetric Standard Model

TL;DR

This paper discusses how the 125 GeV Higgs boson can be viewed as a spin-0 partner of the Z boson within supersymmetric models, unifying gauge and Higgs sectors.

Contribution

It proposes a novel interpretation of the Higgs boson as a supersymmetric partner of the Z, using gauge superfields instead of chiral superfields.

Findings

The 125 GeV boson can be seen as a Z partner under supersymmetry.

Supersymmetry breaking induces a mixing angle affecting this interpretation.

Gauge/BE-Higgs unification is achieved through massive gauge superfields.

Abstract

Supersymmetric extensions of the standard model lead to gauge/BE-Higgs 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 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.
