关于N_f=N_c SQCD中的亚稳真空和直接介导的注记

Comments on the Meta-Stable Vacuum in N_f=N_c SQCD and Direct Mediation

Andrey Katz, Yael Shadmi, Tomer Volansky

摘要:

我们重新讨论了N_f=N_c SQCD及其由Intriligator,Seiberg和Shih(ISS)提出的非超对称极小。我们认为,这种最小值的存在取决于三个不可计算的参数的迹象,并没有证据可以推断变形的理论。我们证明了这一点,通过研究变形的理论,其中涉及额外的规范单。在这种情况下,最小值是不稳定的。我们评论的后果,这种单在模型中的直接调解,特别是在五角大楼的模型。

英文摘要:

We revisit N_f=N_c SQCD and its non-supersymmetric minima conjectured by Intriligator, Seiberg and Shih (ISS). We argue that the existence of such minima depends on the signs of three non-calculable parameters and that no evidence can be inferred by deforming the theory. We demonstrate this by studying a deformation of the theory which involves additional gauge singlets. In this case, the conjectured minimum is destabilized. We comment on the consequences of such singlets in models of direct mediation and in particular in the Pentagon model.
