摘要
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. Howe:ver, 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 p(T) 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.
