Sweet Spot Supersymmetry

Understand

We find that there is no supersymmetric flavor/CP problem, mu-problem, cosmological moduli/gravitino problem or dimension four/five proton decay problem in a class of supersymmetric theories with O(1) GeV gravitino mass.

• The cosmic abundance of the non-thermally produced gravitinos naturally explains the dark matter component of the universe.
• A mild hierarchy between the mass scale of supersymmetric particles and electroweak scale is predicted, consistent with the null result of a search for the Higgs boson at the LEP-II experiments.
• A relation to the strong CP problem is addressed.
