SQCD中提升的亚稳态介导和规范中介
Uplifted Metastable Vacua and Gauge Mediation in SQCD
摘要：
反常的小质量是各种直接规范调解模型的共同特征。这个问题与真空结构理论密切相关。在本文中，我们表明，有质量的SQCD可以有SUSY破缺真空，这是定性不同于国际空间站真空。这些新的真空相对于国际空间站真空的衰变是亚稳态的。我们证明了在这个框架中解决高吉诺质量问题的可能性。我们研究了这些真空的性质，并构造了一个直接规范调解模型的例子。
英文摘要：
Anomalously small gaugino masses are a common feature of various models of direct gauge mediation. This problem is closely related to the vacuum structure of the theory. In this paper we show that massive SQCD can have SUSY-breaking vacua which are qualitatively different from the ISS vacuum. These novel vacua are metastable with respect to decay to the ISS vacuum. We demonstrate the possibility of addressing the gaugino mass problem in this framework. We study the properties of these vacua and construct an example of a model of direct gauge mediation.
