New results for the Inert Doublet Model

Abstract

New results for the Inert Doublet Model (IDM) are discussed. It is very special among the $D$-symmetric 2HDMs, offering a good DM candidate. New unitarity constraints were derived for the IDM and SM-like light Higgs boson scenario in the Mixed Model.

Comments: 7 pages, 3 eps figures. An error was found in calculations, which modified conclusions for the Mixed Model. The current version contains corrections described in Erratum
