摘要

Higgs Portal dark matter have been supposed due to the two facts that dark matter has a gravitational force and has no strong interaction and electromagnetic interaction.A natural logic is the possibility of hiding dark matter.That is,the dark matter does not have the interaction of standard model.Dark matter may be hidden sector.The standard model particles are in the visible sector.The Higgs sector of the Standard Model enjoys a special feature that it can couple to the hidden sector at the renormalizable level.Ref.[1]has discussed the relationship between the standard model and hidden sector.Let H be Higgs field andΦ,be the“hidden Higgs field”in hidden sector.There are a“Higgs portal”interaction term between H andΦas Vportal=λhΦH+HΦ+Φ.
