摘要:

为了满足当前FCNC和CP破坏界限,超对称风味结构不能是通用的。一个有趣的解决方案,这些超对称性和CP问题在于使用SU(3)族对称性,自发打破CP对称。这种模型的典型观测量是电偶极矩和LFV过程。此外,这些模型对中性介子混合中的CP破坏也有贡献。我们展示了如何后者可以用来限制允许的超对称性参数空间,并诱导LFV和EDM预测之间的相关性。

英文摘要:

In order to satisfy current FCNC and CP violation bounds, SUSY flavour structures cannot be generic. An interesting solution to these SUSY Flavour and CP Problems lies on the use of an SU(3) family symmetry which spontaneously breaks CP symmetry. Typical observables of such a model are electric dipole moments and LFV processes. In addition, these models can give contributions to CP violation in neutral meson mixing. We show how the latter can be used to restrict the allowed SUSY parameter space, and induce correlations between LFV and EDM predictions.
