Update on the CP-Violating Inert-Doublet Model

Understand

We have updated a recently proposed extension of the Inert Doublet Model.

• The extension amounts to the addition of an extra non-inert scalar doublet.
• The model thus offers a possibility of CP violation in the scalar sector and a candidate for the Dark Matter.
• The recent XENON100 direct-detection experiment excludes a considerable range of medium-low dark-matter masses, leaving only as viable very low masses of order 5-10 GeV, as well as the regions from \sim 60 to \sim 110 GeV, and above \sim 530 GeV.
