Dark matter in a singlet-extended inert Higgs-doublet model
Dark matter in a singlet-extended inert Higgs-doublet model
In this work, we consider an extension of the Standard Model with an inert Higgs doublet and a real scalar singlet, in order to address problems around the origin of dark matter (DM). In this model, the lightest among the $CP$-odd and $CP$-even neutral inert components plays the role of …
