A new dark matter candidate [1,2] has couplings to Z and W gauge bosons that are in a sense weaker than those of other popular WIMPs (weakly interacting massive particles) -- principally the neutralino -- since they are either second-order or momentum-dependent. This may explain why dark matter particles have not yet been observed. On the other hand, this new particle should be observable in all the experiments that are currently searching for dark matter particles. For example, at the LHC, the CMS and ATLAS experiments should focus on events in which virtual Z bosons, or else W or Z boson pairs, produce particle- antiparticle pairs involving the new spin 1/2 neutral particle proposed here, which are then detected as missing transverse energy. The well-defined couplings and mass of this new WIMP provide a well-defined signature of its creation or annihilation, even though the cross-sections are smaller than for e.g. neutralinos.
