讨论了具有CP破坏的单态-双态费米子暗物质模型。在这个模型中，CP破坏产生了暗物质与标准模型希格斯玻色子的伪标量相互作用。由于存在伪标量相互作用，该模型可以避开暗物质直接探测实验的强约束，同时保持热遗迹场景的成功。CP破坏还可以预测暗物质间接探测实验和电偶极矩(EDM)中的信号，这些信号可以与当前的上限一样大。探讨了直接检测实验、间接检测实验和电子电火花加工的局限性和发展前景。我们还研究了希格斯势的稳定性。综合这些观测数据，我们发现重暗物质是不受欢迎的。我们还发现，如果将来的电子电火花实验达到O(10-32)e cm，就有可能通过直接探测实验和对电子电火花的测量相结合来探测希格斯漏斗区域。
We discuss the singlet-doublet fermion dark matter model with CP-violation. In this model, the CP violation generates a pseudoscalar interaction of dark matter with the standard model-Higgs boson. Thanks to the pseudoscalar interaction, the model can evade the strong constraint from the dark matter direct detection experiments while keeping the success of the thermal relic scenario. The CP violation also predicts signals in dark matter indirect detection experiments and electric dipole moments (EDM) that can be as large as the current upper bound. We investigate the constraints and prospects of the direct detection experiments, the indirect detection experiment, and the electron EDM. We also investigate the stability of the Higgs potential. Combining these observables, we find that heavy dark matter is disfavored. We also find it is possible to probe the Higgs funnel region by the combination of the direct detection experiments and the measurements of the electron EDM if experiments for the electron EDM reach to O(10-32) e cm in future.
