超对称性对族对称性预测性的思考
Supersymmetric Musings on the Predictivity of Family Symmetries
摘要：
在超引力框架下讨论了族对称性对软超对称破缺参量的预言性。我们发现，信使部门和超对称性破缺隐藏部门的未知细节进入软参数，很难获得强大的预测。我们发现，有特定的选择信使领域，可以提高软参数的预测性。
英文摘要：
We discuss the predictivity of family symmetries for the soft supersymmetry breaking parameters in the framework of supergravity. We show that unknown details of the messenger sector and the supersymmetry breaking hidden sector enter into the soft parameters, making it difficult to obtain robust predictions. We find that there are specific choices of messenger fields which can improve the predictivity for the soft parameters.
