  Diverse experimental constraints now motivate models of supersymmetry
breaking in which some superpartners have masses well above the weak scale.
Three alternatives are focus point supersymmetry and inverted hierarchy models,
which embody a naturalness constraint, and the more recent framework of split
supersymmetry, which relaxes that constraint. Many aspects of their
phenomenology are very similar. They can be distinguished, however, through
detailed study of superoblique parameters, the Higgs potential and other
observables.
