Abstract

We consider a recently proposed supersymmetric model based on the discrete Q6 family group. Because of the family symmetry and spontaneous CP violation, the electric dipole moment, the CP violation in the mixing of the neutral mesons, and the dark matter mass mDM are closely related. This triangle relation is controlled by the size of the μ parameters. Loop effects can give rise to large contributions to the soft mass insertions, and we find that the model allows a large CP violation in the B0 system. 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, and CP violations in K0 as well as B0 mixing, the triangle relation yields the following bound on the dark matter candidate: 0.12  TeV
