Confronting dark matter co-annihilation of Inert two Higgs Doublet Model with a compressed mass spectrum

Abstract We perform a comprehensive analysis for the light scalar dark matter (DM) in the Inert two Higgs doublet model (i2HDM) with compressed mass spectra, small mass splittings among three ℤ2 odd particles — scalar S, pseudo-scalar A, and charged Higgs H ± . In such a case, the co-annihilation pr...
