abstract = "We show that the 't Hooft-Polyakov monopole model in the hidden sector with Higgs portal interaction makes a viable dark matter model, where monopole and massive vector dark matter (VDM) are stable due to topological conservation and the unbroken subgroup U(1)X. A right amount of VDM thermal relic can be obtained via s-channel resonant annihilation. In addition, the dark photon associated with unbroken U(1)X contributes to the radiation energy density at present, giving ΔNeνff ∼ 0.1 as the extra relativistic neutrino species.",
