论文摘要

标准模型的超对称性扩展在10 TEV上方的标量超级零部队是充分的动机,因为Higgs玻色子质量可以通过量子校正来解释,同时保持规格耦合统一。如果超对称断裂通过异常介导传递到仪表,则与标量质量相比,升压块被抑制了循环,最轻的超对称粒子是higgsino或wino,这可能是暗物质。在此设置中,我们确定了重现观察到的希格斯玻色子质量和暗物质的热丰度的参数空间区域。我们分析了gaugino质量参数对电子偶极矩(EDM)和暗物质散射横截面的复杂相的影响。我们发现,对于高达10 PEV的标量质量以及复杂相的任何大小,具有Higgsino暗物质的模型即可到达计划中的实验 - 通过电子EDM通过电子EDM和Lux-Zeplin通过深色物质直接检测 - 具有互补的发现电位,以及带有Wino Dark Matter的Dark Matters EDM EDM EDM EDM实验的模型。

Supersymmetric extensions of the Standard Model with scalar superpartners above 10 TeV are well motivated since the Higgs boson mass can be explained by quantum corrections while maintaining gauge coupling unification. If supersymmetry breaking is transmitted to gauginos via anomaly mediation, the gaugino masses are loop suppressed compared to scalar masses, and the lightest supersymmetric particle is the Higgsino or wino, which can be the dark matter. In this setup, we identify the regions of parameter space that reproduce the observed Higgs boson mass and the thermal abundance of dark matter. We analyze the effects of complex phases in the gaugino mass parameters on the electron electric dipole moment (EDM) and the dark matter scattering cross section. We find that, for scalar masses up to 10 PeV and any size of the complex phases, the model with Higgsino dark matter is within reach of planned experiments -- Advanced ACME via electron EDM and LUX-ZEPLIN via dark matter direct detection -- with complementary discovery potentials, and the model with wino dark matter is within reach of future electron EDM experiments.
