Abstract: Most LHC searches to date have focused on new physics signatures motivated by possible solutions to the hierarchy, naturalness and dark matter puzzles. I consider some candidates for new states that, although not well-motivated from this standpoint, are obvious possibilities that current search strategies would miss. In particular I focus on vector representations of fermions in multiplets of SU(2)_L with a lightest neutral state. Standard search strategies would fail to find such particles because of the small one-loop-level splitting between charged and neutral states. I discuss the possible LHC search strategies and discovery potential, as well as the application to an anomaly mediated supersymmetric spectrum.
