我们研究了隐藏扇区中具有双规子凝聚的超对称模型，其中规子耦合依赖于超弦理论的两个光模。我们对这类模型进行了详细的分析，并证明了模场不存在具有有限真空值的稳定超对称极小值。相反，我们发现超对称破缺发生在模稳定和负真空能量的情况下。这就产生了模主导的软超对称破缺项。为了实现稍微正的（或消失的）真空能量，我们增加了提升的潜力。讨论了模的真空期望值的提升不改变模的真空期望值以及超对称破缺的上述特征。
We study supersymmetric models with double gaugino condensations in the hidden sector, where the gauge couplings depend on two light moduli of superstring theory. We perform a detailed analysis of this class of model and show that there is no stable supersymmetric minimum with finite vacuum values of moduli fields. Instead, we find that the supersymmetry breaking occurs with moduli stabilized and negative vacuum energy. That yields moduli-dominated soft supersymmetry breaking terms. To realize slightly positive (or vanishing) vacuum energy, we add uplifting potential. We discuss uplifting does not change qualitatively the vacuum expectation values of moduli and the above feature of supersymmetry breaking.
