(额外)普通仪表调解

(Extra)Ordinary Gauge Mediation

Clifford Cheung, A. Liam Fitzpatrick, David Shih

摘要:

我们研究模型的“(额外的)普通规范调解”,其中包括采取普通规范调解和扩展的信使超势,包括所有重正耦合符合SM规范不变性和R-对称性。我们对所有这些模型进行了分类,发现它们的现象学与普通的规范中介有很大的不同。一些亮点包括:任意修改的夸克/slepton质量关系,小亩和希格斯诺NLSP的,并有可能少于一个有效的信使。我们还展示了这些模型如何自然地导致非常简单的直接规范调解的例子,超对称性和R-对称性破缺发生在一个隐藏的部门,但由于信使部门本身的动态。

英文摘要:

We study models of "(extra)ordinary gauge mediation," which consist of taking ordinary gauge mediation and extending the messenger superpotential to include all renormalizable couplings consistent with SM gauge invariance and an R-symmetry. We classify all such models and find that their phenomenology can differ significantly from that of ordinary gauge mediation. Some highlights include: arbitrary modifications of the squark/slepton mass relations, small mu and Higgsino NLSP's, and the possibility of having fewer than one effective messenger. We also show how these models lead naturally to extremely simple examples of direct gauge mediation, where SUSY and R-symmetry breaking occur not in a hidden sector, but due to the dynamics of the messenger sector itself.
