Exploring the CP-Violating Inert-Doublet Model

Understand

We have explored properties of an extension of the Inert Doublet Model by the addition of an extra non-inert scalar doublet.

• The model offers a possibility of CP violation in the scalar sector and a candidate for the Dark Matter.
• Allowed regions in the plane spanned by the mass of the Dark-Matter particle and the lightest neutral Higgs particle have been identified, and constraints from direct and indirect-detection experiments have been studied.
• For favorable parameter regions one may observe long-lived charged particles produced at the LHC.
