Gauge Extensions of Supersymmetric Models and Hidden Valleys

Understand

Supersymmetric models with extended group structure beyond the standard model are revisited in the framework of general gauge mediation.

• Sum rules for sfermion masses are shown to depend genuinely on the group structure, which can serve as important probes for specific models.
• The left-right model and models with extra U(1) are worked out for illustrations.
• If the couplings of extra gauge groups are small, supersymmetric hidden valleys of the scale 10-100 GeV can be naturally constructed in companion of a TeV-scale supersymmetric visible sector.
