Update on the CP-Violating Inert-Doublet Model
Abstract
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.
