dc.description.abstract Once a parity is introduced in unparticle physics, under which unparticle provided in a hidden conformal sector is odd while all Standard Model particles are even, unparticle can be a suitable candidate for the cold dark matter (CDM) in the present universe through its coupling to the Standard Model Higgs doublet. We find that for Higgs boson mass in the range, 114.4GeV≲mₕ≲250GeV, the relic abundance of unparticle with mass 50GeV≲mᵤ≲80GeV can be consistent with the currently observed CDM density. In this scenario, Higgs boson with mass mₕ≲160GeV dominantly decays into a pair of unparticles and such an invisible Higgs boson may be discovered in future collider experiments. en_US
