摘要：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 60 to 110 GeV, and above 530 GeV. For favorable parameter regions one may observe related long-lived charged particles produced at the LHC.
