论文摘要
我们向Nelson-Seiberg Theorem提出了一种新型的反例。这是一个通用的R-对称Wess-Zumino模型,具有九个手性超级场,包括一个R-Charge 2的一个场和无R-Charge 0字段。与以前的反例一样,该模型给出了一组简并对称的超对称真空吸尘器,对一对相对的R带电场具有非零的期望值。然而,这些字段之一在超电势中四处显地,许多其他非零R-Charges的领域在真空吸引了非零的期望值,因此该模型逃脱了以前文献中建立的反例的足够条件。因此,在通用模型中,R-符号与超对称性破坏的关系中仍然存在开放的问题。
We present a new type of counterexample to the Nelson-Seiberg theorem. It is a generic R-symmetric Wess-Zumino model with nine chiral superfields, including one field of R-charge 2 and no R-charge 0 field. As in previous counterexamples, the model gives a set of degenerate supersymmetric vacua with a non-zero expectation value for a pair of oppositely R-charged fields. However, one of these fields appears quadratically in the superpotential, and many other fields with non-zero R-charges gain non-zero expectation values at the vacuum, and so this model escapes the sufficient condition for counterexamples established in previous literature. Thus there are still open problems in the relation of R-symmetries to supersymmetry breaking in generic models.
