Current status and future prospects of the singlet-doublet dark matter model with $CP$ violation

Understand

We discuss the singlet-doublet fermion dark matter model with CP-violation.

• In this model, the CP-violation generates a pseudo-scalar interaction of dark matter with the SM-Higgs boson.
• Thanks to the pseudo-scalar 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.
