Abstract We propose a scenario of currys dyson dc40 dark sector described by a hidden SU(2) gauge symmetry which is broken by a vacuum expectation value(VEV) of a scalar multiplet.We discuss a general mass relation among SU(2) gauge bosons after spontaneous symmetry breaking which is determined by weight of gauge group representation associated with a scalar multiplet developing VEV.Then a model with quintet and triplet scalar fields is discussed in which hidden gauge boson can be dark matter(DM) stabilized by remnant discrete Z 2 symmetry motovox scooter parts and resonant dark matter annihilation is realized by mass relation between DM and mediator.We estimate relic density and spin independent DM-nucleon scattering cross section searching for allowed parameter region.
