Aspects of Z'-mediated Supersymmetry Breaking

Understand

In a recent paper, we proposed the possibility that supersymmetry breaking is communicated dominantly via a U(1)' vector multiplet.

• We also required that the U(1)' plays a crucial role in solving the mu problem.
• We discuss here in detail both the construction and the phenomenology of one class of such models.
• The low energy spectrum generically contains heavy sfermions, Higgsinos and exotics ~10-100 TeV; an intermediate M_Z' ~ 3-30 TeV; light gauginos ~100-1000 GeV, of which the lightest can be wino-like; a light Higgs with a mass of ~140 GeV; and a singlino which can be very light.
