The Least Supersymmetric Standard Model

Understand

We propose the minimal (Least) version of the Supersymmetric Standard Model which can solve the hierarchy problem in the same way as the so-called Minimal Supersymmetric Standard Model (MSSM) and presents solutions to some of its problems.

• Supersymmetry is broken in a secluded sector and mediated to the observable sector by messengers of a gauge group G under which the first two generations transform.
• The group G spontaneously breaks (almost) supersymmetrically at a scale at most a few orders of magnitude below the scale of gauge messengers M_*\sim 10^{15} GeV.
• By gauge mediation sfermions of the first two generations acquire supersymmetry breaking masses \hat m \sim 10 TeV.
