本文主要研究E6 × SU(2)F × U(1)超对称(SUSY)大统一理论(GUT)模型。在这个模型中,现实的汤川层次和混合实现通过引入所有允许的相互作用?(1)系数此外,我们可以取停止质量小于其他的sfermion质量。这类谱称为自然超对称型费米子质谱,能抑制超对称性对味变中性流的贡献,同时稳定弱标度。然而,光阻预测大的上夸克CEDM和停止的贡献不解耦。由于存在Kobayashi-Maskawa相,即使所有的超对称破缺参数和Higgsino质量参数μ都是真实的,停止对上夸克CEDM的贡献也受到严重限制.在这个模型中,真实的上汤川耦合实现在大统一尺度,因为自发CP破坏。因此,CEDM边界是满意的,虽然汤川耦合是复杂的超对称尺度通过重整化方程组的影响。我们...
We focus on E6 × SU(2)F × U(1)A supersymmetric (SUSY) grand unified theory (GUT) model. In this model, realistic Yukawa hierarchies and mixings are realized by introducing all allowed interactions with ?(1) coefficients. Moreover, we can take stop mass is smaller than the other sfermion masses. This type of spectrum called by natural SUSY type sfermion mass spectrum can suppress the SUSY contributions to flavor changing neutral current (FCNC) and stabilize weak scale at the same time. However, light stop predicts large up quark CEDM and stop contributions are not decoupled. Since there is Kobayashi-Maskawa phase, stop contributions to the up quark CEDM is severely constrained even if all SUSY breaking parameters and Higgsino mass parameter μ are real. In this model, real up Yukawa couplings are realized at the GUT scale because of spontaneous CP violation. Therefore CEDM bounds are satisfied, although up Yukawa couplings are complex at the SUSY scale through the renormalization equation group effects. We ...
