Electroweak symmetry breaking from supersymmetry breaking with a bosonic seesaw mechanism

We introduce the idea of bosonic seesaw mechanism in analogy with the seesaw mechanism. Bosonic seesaw is a new symmetry breaking mechanism, and we apply it to explain electroweak symmetry breaking as an inevitable consequence of supersymmetry breaking. The breaking of electroweak symmetry occurs at tree level once supersymmetry is broken. Absence of color/charge breaking in this model is related to doublet-triplet splitting in the grand unified theory. An extension of the minimal supersymmetric standard model with a weak triplet shows very interesting results, especially when {mu}=0. It provides natural understanding of why we have only electroweak symmetry breaking rather than having color/charge breaking. In the limit {mu}=0, the model predicts very light chargino mass, 104 GeV, while Higgs is heavy, 130 GeV.
