Electroweak Symmetry Breaking from SUSY Breaking with Bosonic See-Saw Mechanism
Hyung Do Kim
Abstract
We introduce the idea of bosonic see-saw mechanism in analogy with the see-saw mechanism. Bosonic see-saw 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 grand unified theory. An extension of MSSM with a weak triplet shows very interesting results especially when mu =0. It provides the most 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.
