英文摘要:
We consider an extension of the Higgs sector in the standard model with six Higgs doublets. The gauge couplings are unified without supersymmetry in this model. The lightest of the extra Higgs particles, being stabilized by a discrete symmetry imposed from the outset, presents a plausible candidate for dark matter. For a specific acceptable benchmark point, we show that the model is viable regarding the constraints of relic density, direct detection, and invisible Higgs decay. We comment on the mean free path of the dark matter candidate.
