摘要:

在一个规范介导的颤抖样模型的框架下,标准模型的味道纹理可以自然地产生。该模型-像MSSM一样-在参数空间中还有一个区域,其中最轻的希格斯质量由重的停止环提供,这反过来又将平均夸克质量标度设置为10-20 TeV。我们进行了仔细的风味分析,以检查这种类型的温和分裂超对称性是否通过所有风味的限制,容易想象在原来的类型的分裂超对称性。有趣的是,它原来是在边界上的几个约束,特别是,分支比的mu -> e γ,如果一阶复杂的相位被假定,也是100 K中子和电子EDM。此外,我们认为统一以及暗物质的候选人,特别是引力子。最后,我们提供了一个封闭的形式公式的软物质的质量在任意表示的任何规范组在一个通用的箭袋状模型与一般的信使部门。

英文摘要:

In the framework of a gauge mediated quiver-like model, the standard model flavor texture can be naturally generated. The model - like the MSSM - has furthermore a region in parameter space where the lightest Higgs mass is fed by heavy stop loops, which in turn sets the average squark mass scale near 10-20 TeV. We perform a careful flavor analysis to check whether this type of mild-split SUSY passes all flavor constraints as easily as envisioned in the original type of split SUSY. Interestingly, it turns out to be on the border of several constraints, in particular, the branching ratio of mu -> e gamma and, if order one complex phases are assumed, also epsilon_K neutron and electron EDM. Furthermore, we consider unification as well as dark matter candidates, especially the gravitino. Finally, we provide a closed-form formula for the soft masses of matter in arbitrary representations of any of the gauge groups in a generic quiver-like model with a general messenger sector.
