Vector dark matter from split SU(2) gauge bosons
  We propose a vector dark matter model with an exotic dark SU(2) gauge group.
Two Higgs triplets are introduced to spontaneously break the symmetry. All of
the dark gauge bosons become massive, and the lightest one is a viable vector
DM candidate. Its stability is guaranteed by a remaining Z_2 symmetry. We study
the parameter space constrained by the Higgs measurement data, the dark matter
relic density, and direct and indirect detection experiments. We find numerous
parameter points satisfying all the constraints, and they could be further
tested in future experiments. Similar methodology can be used to construct
vector dark matter models from an arbitrary SO(N) gauge group.
