Flavor Symmetry Based MSSM (sMSSM): Theoretical Models and Phenomenological Analysis

Understand

We present a class of supersymmetric models in which symmetry considerations alone dictate the form of the soft SUSY breaking Lagrangian.

• We develop a class of minimal models, denoted as sMSSM -- for flavor symmetry-based minimal supersymmetric standard model, which respect a grand unified symmetry such as SO(10) and a non-Abelian flavor symmetry H which suppresses SUSY-induced flavor violation.
• Explicit examples are constructed with the flavor symmetry being gauged SU(2)_H and SO(3)_H with the three families transforming as 2 + 1 and 3 representations respectively.
• A simple solution is found in the case of SU(2)_H for suppressing the flavor violating D--terms based on an exchange symmetry.
