N2 - We consider a class of models in which supersymmetry breaking is communicated dominantly via a U(1)′ gauge interaction, which also helps solve the μ 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′∼10-100TeV, light gauginos∼100-1000GeV, a light Higgs boson∼140GeV, and a light singlino. A specific set of U(1)′ charges and exotics is analyzed, and we present five benchmark models. The implications for the gluino lifetime, cold dark matter, and the gravitino and neutrino masses are discussed.
