  We consider a class of models in which supersymmetry breaking is communicated
dominantly via a U'(1) gauge interaction, which also helps solve the \mu
problem. Such models can emerge naturally in top-down constructions and are a
version of split supersymmetry. The spectrum contains heavy sfermions,
Higgsinos, exotics, and Z' ~ 10-100 TeV; light gauginos ~ 100-1000 GeV; a light
Higgs ~ 140 GeV; and a light singlino. A specific set of U'(1) charges and
exotics is analyzed, and we present five benchmark models. Implications for the
gluino lifetime, cold dark matter, and the gravitino and neutrino masses are
discussed.
