  Weakly interacting massive particle (WIMP) is well known to be a good
candidate for dark matter, and it is also predicted by many new physics models
beyond the standard model at the TeV scale. We found that, if the WIMP is a
vector particle (spin one particle) which is associated with some gauge
symmetry broken at the TeV scale, the higgs mass is often predicted to be
120--125 GeV, which is very consistent with the result of higgs searches
recently reported by ATLAS and CMS collaborations at the Large Hadron Collider
experiment. In this letter, we consider the vector WIMP using a non-linear
sigma model in order to confirm this result as general as possible in a
bottom-up approach. Near-future prospects to detect the vector WIMP at both
direct and indirect detection experiments of dark matter are also discussed.
