论文摘要
Nelson-Seiberg定理将R-symorties与F-Term Supersymmetry Breaking联系起来，并为超出标准模型以外的新物理模型构建提供了指导规则。该定理的修订为具有多项式超电势模型中的超对称性破裂提供了必要和充分的条件。这项工作重新审视了定理，以包括具有非多物质超电势的模型。使用通用的R-对称超电势，场空间起源的奇异性既意味着R-对称性断裂和超对称性破裂。我们为超对称性破裂提供了普遍的必要条件，适用于扰动和非扰动模型。
The Nelson-Seiberg theorem relates R-symmetries to F-term supersymmetry breaking, and provides a guiding rule for new physics model building beyond the Standard Model. A revision of the theorem gives a necessary and sufficient condition to supersymmetry breaking in models with polynomial superpotentials. This work revisits the theorem to include models with nonpolynomial superpotentials. With a generic R-symmetric superpotential, a singularity at the origin of the field space implies both R-symmetry breaking and supersymmetry breaking. We give a generalized necessary and sufficient condition for supersymmetry breaking which applies to both perturbative and nonperturbative models.
