Supersymmetric Alignment Models for $(g-2)_{\mu}$

Understand

Hierarchical masses of quarks and leptons are addressed by imposing horizontal symmetries.

• In supersymmetric Standard Models, the same symmetries play a role in suppressing flavor violating processes induced by supersymmetric particles.
• Combining the idea of spontaneous CP violation to control contributions to electric dipole moments (EDMs), the mass scale of supersymmetric particles can be lowered.
• We present supersymmetric models with $U(1)$ horizontal symmetries and discuss CP and flavor constraints.
