研究了类双星中性伴子暗物质通过重Higgs漏斗湮灭的$CP$-破坏最小超对称标准模型中的电偶极矩。受当前实验结果的启发，特别是标准模型的希格斯玻色子的测量质量，我们考虑一个质量停止质量约为10 TeV的质谱。对于其他的sfermions，我们认为质量约为100 TeV。我们发现，$CP$-违反相位的顺序为10度的高吉诺和希格斯诺质量参数是一致的，与电流约束的电子，中子和汞的EDM。它们在未来的实验范围内。我们还表明，$CP$-破坏相位的影响引起的DM-核子散射截面的一个因素的差异。
We investigate electric dipole moments (EDMs) in a $CP$-violating minimal supersymmetric standard model with the binolike neutralino dark matter (DM) annihilating through the heavy Higgs funnel. Motivated by the current experimental results, in particular, the measured mass of the standard model-like Higgs boson, we consider a mass spectrum with stop masses of about 10 TeV. For the other sfermions, we consider masses of about 100 TeV. We show that $CP$-violating phases of the order of ten degrees in gaugino and Higgsino mass parameters are consistent with the current bound by EDMs of the electron, the neutron, and the mercury. They are within the reach of future experiments. We also show that effects of $CP$-violating phases induce a difference in DM-nucleon scattering cross section by a factor.
