标题： Fermion Masses and Gauge Mediated Supersymmetry Breaking from a Single U(1)

摘要： 我们提出一个味的超对称模型。一个单独的U(1)规范群既负责生成味谱，又将超对称性破缺传递到可见扇区。通过在squarks中使用“有效超对称”谱，部分克服了味改变中性流的问题，其中前两代非常重。所有质量都是动态生成的，该理论是完全可重整化的。该模型包含一个简单的Froggatt-Nielsen扇区，并通过规范介导传递超对称性破缺，而不需要单独的信使扇区。通过强制理论与SU(5)大统一相容，该模型预测了一个大的tan beta和一个无质量的上夸克。在尊重K系统中CP破坏的实验限制的同时，该模型导致了B-(B bar)混合以及B衰变振幅中CP破坏的显著增强。 显示英文摘要

摘要： We present a supersymmetric model of flavor. A single U(1) gauge group is responsible for both generating the flavor spectrum and communicating supersymmetry breaking to the visible sector. The problem of Flavor Changing Neutral Currents is overcome, in part using an `Effective Supersymmetry' spectrum among the squarks, with the first two generations very heavy. All masses are generated dynamically and the theory is completely renormalizable. The model contains a simple Froggatt-Nielsen sector and communicates supersymmetry breaking via gauge mediation without requiring a separate messenger sector. By forcing the theory to be consistent with SU(5) Grand Unification, the model predicts a large tan beta and a massless up quark. While respecting the experimental bounds on CP violation in the K-system, the model leads to a large enhancement of CP violation in B-(B bar) mixing as well as in B decay amplitudes.
