Phenomenology of Supersymmetric Models with a Symmetry-Breaking Seesaw
  Mechanism
  We explore phenomenological implications of the minimal supersymmetric
standard model (MSSM) with a strong supersymmetry breaking trilinear term.
Supersymmetry breaking can trigger electroweak symmetry breaking via a
symmetry-breaking seesaw mechanism, which can lead to a low-energy theory with
multiple composite Higgs bosons. In this model, the electroweak phase
transition can be first-order for some generic values of parameters.
Furthermore, there are additional sources of CP violation in the Higgs sector.
This opens the possibility of electroweak baryogenesis in the strongly coupled
MSSM. The extended Higgs dynamics can be discovered at Large Hadron Collider or
at a future linear collider.
