通用信使仪表调解

General Messenger Gauge Mediation

Thomas T. Dumitrescu, Zohar Komargodski, Nathan Seiberg, David Shih

摘要:

我们讨论的规范调解理论,其中隐藏的部门由两个子部门是弱耦合到彼此。一个扇区由信使组成,另一个扇区打破了超对称性。每个扇区本身可以是强耦合的。我们为这些理论提供了一个统一的框架,并讨论了它们在不同环境中的预测。我们展示了这个框架如何结合所有已知的信使模型。在弱耦合信使通过超势与spurons相互作用的情况下,我们证明了sfermion质量平方是正的,而且sfermion质量与gaugino质量的比值存在一个下界。

英文摘要:

We discuss theories of gauge mediation in which the hidden sector consists of two subsectors which are weakly coupled to each other. One sector is made up of messengers and the other breaks supersymmetry. Each sector by itself may be strongly coupled. We provide a unifying framework for such theories and discuss their predictions in different settings. We show how this framework incorporates all known models of messengers. In the case of weakly-coupled messengers interacting with spurions through the superpotential, we prove that the sfermion mass-squared is positive, and furthermore, that there is a lower bound on the ratio of the sfermion mass to the gaugino mass.
