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 posssible 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 SM Higgs boson h.
