广泛接受的Nelson-Seiberg定理将r对称与超对称破缺真空联系起来，为超对称模型的建立提供了指导，这是标准模型之外最有前途的物理学。对于具有微扰超势的Wess-Zumino模型，我们将该定理修正为SUSY破缺的一个充分必要条件，该条件可以在求解真空之前很容易地进行检验。修正后的定理为构造超对称性破缺和超对称性真空提供了一个强有力的工具，并在低能超对称性模型的建立和弦现象学中提供了许多实际应用。
The well-accepted Nelson-Seiberg theorem relates R-symmetries to supersymmetry (SUSY) breaking vacua, and provides a guideline for SUSY model building which is the most promising physics beyond the Standard Model. In the case of Wess-Zumino models with perturbative superpotentials, we revise the theorem to a combined necessary and sufficient condition for SUSY breaking which can be easily checked before solving the vacuum. The revised theorem provides a powerful tool to construct either SUSY breaking or SUSY vacua, and offers many practicable applications in low energy SUSY model building and string phenomenology.
