我们考虑了最近提出的一个基于离散族群的超对称模型。由于介子族的对称性和自发破坏,电偶极矩、中性介子混合中的破坏和暗物质质量密切相关。这种三角关系由参数的大小控制。环效应对软质量插入有较大贡献,我们发现模型允许大的破坏。它的大小与D0和CDF最近的实验观测相当,并且在最初的几年里可以在LHCb上观察到它。如果参数空间受到中子电偶极矩、变味中性流以及混合中的违反的约束,三角关系产生暗物质候选者的以下界限:,这在LHC上是直接可观察的。我们还计算了在LHCb上可观察到的,其中是半轻子的不对称性。
We consider a recently proposed supersymmetric model based on the discretefamily group. Because of the family symmetry and spontaneousviolation, the electric dipole moment, theviolation in the mixing of the neutral mesons, and the dark matter massare closely related. This triangle relation is controlled by the size of theparameters. Loop effects can give rise to large contributions to the soft mass insertions, and we find that the model allows a largeviolation in thesystem. Its size is comparable with the recent experimental observations by D0 and CDF, and it could be observed at the LHCb in the first years. If the parameter space is constrained by the neutron electric dipole moment, flavor changing neutral currents, andviolations inas well asmixing, the triangle relation yields the following bound on the dark matter candidate:, which is directly observable at the LHC. We also compute, which is observable at the LHCb, whereis the semileptonicasymmetry for thesystem.
