摘要：

在最近的一篇论文中，我们提出了超对称破缺主要通过U（1）'矢量多重态传递的可能性。我们还要求U（1）'在解决μ问题中起着至关重要的作用。我们在这里详细讨论的建设和一类这样的模型的现象。低能谱一般包含~10-100 TeV的重sfermions，Higgsinos和exotic，~ 3-30 TeV的中间M_Z'，~100-1000 GeV的轻gauginos，其中最轻的可以是wino，~140 GeV的轻Higgs，和可能很轻的singlino。我们提出了一组可能的一致的收费选择。几个基准模型被用来证明特征的现象学特征。特别注意的是专门有趣的LHC签名，如胶子衰变和电弱离子的衰变模式。中微子质量，奇异衰变，R-宇称，规范统一，引力子质量的影响进行了简要的讨论。

英文摘要：

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. We present a set of possible consistent charge choices. Several benchmark models are used to demonstrate characteristic phenomenological features. Special attention is devoted to interesting LHC signatures such as gluino decay and the decay patterns of the electroweak-inos. Implications for neutrino masses, exotic decays, R-parity, gauge unification, and the gravitino mass are briefly discussed.
