Abstract

In supersymmetric models, W-inos, partners of the SU(2) gauge bosons, may be the lightest supersymmetric particles. For generic parameters, charged and neutral W-inos are highly degenerate. Charged W-inos travel macroscopic distances, but can decay to neutral W-inos and extremely soft leptons or pions before reaching the muon chambers, thereby circumventing conventional trigger requirements. However, these charginos are detectable, and can be triggered on when produced in association with jets. In addition, we propose a new trigger for events with a high pT track and low hadronic activity. For Tevatron Run II with luminosity 2 fb-1, the proposed searches can discover W-inos with masses up to 300 GeV and explore a substantial portion of the parameter space in sequestered sector models.
