Abstract

If the standard model of particle interactions is extended to include a second scalar doublet [H+,(H0+iA0)/√2], which is odd under an unbroken Z2 discrete symmetry, it may be called the dark scalar doublet, because its lightest neutral member, say H0, is one possible component for the dark matter of the Universe. We discuss the general phenomenology of the four particles of this doublet, without assuming that H0 is the dominant source of dark matter. We also consider the impact of this dark scalar doublet on the phenomenology of the standard-model Higgs boson h.
