LHC searches for non-chiral weakly charged multiplets

In this paper we consider vector representations of fermions in multiplets of SU(2) L with a lightest neutral state, a notable example of which is the wino LSP in anomaly-mediated models. Because of the expected small one-loop-level splitting between charged and neutral states, the path length in the detector is finite but short so the signature is distinctive but challenging. Our analysis determines the LHC reach of models with additional weakly charged vector-like matter using similar search strategies to existing studies of some specific models. Currently planned search strategies would fail to find such particles, although early LHC data could be used to better understand our signal and possible backgrounds.
