Phenomenology of Supersymmetric Models with a Symmetry-Breaking Seesaw Mechanism

Understand

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.
