- Abstract
An analysis of the Higgs boson decay rates to γγ and Zγ in the Inert Doublet Model is presented. We study the correlation between the two rates and perform extended analysis of the two-photon rate (Rγγ). We study both the possibility of enhancing and suppressing Rγγ, and find constraints for masses of the scalar particles (in particular the dark matter (DM) candidate and the charged scalar) and their couplings to the Higgs boson. We also combine the resulting constraints with those following from the WMAP measurements of the DM relic density, obtaining stringent constraints on different dark matter scenarios.
