A search for chargino-neutralino production at the Fermilab Tevatron Collider
- New Mexico Univ., Albuquerque, NM (United States)
We have searched for evidence of supersymmetry with the Collider Detector at Fermilab using trilepton events in p$$\bar{p}$$ collisions at √s = 1.8 TeV. In the Minimal Supersymmetric Standard Model (MSSM), we expect trilepton events from chargino-neutralino ($$\tilde{χ}$$±1$$\tilde{χ}$$02) pair production, with subsequent decay into leptons. In all possible combinations of electron and muon channels, we observe no candidate events in 107 pb-1 of data. We present limits on chargino and neutralino production within the framework of a supergravity inspired MSSM: σ$$\tilde{χ}$$±1$$\tilde{χ}$$02 ∙ BR($$\tilde{χ}$$±1$$\tilde{χ}$$02 → 3l + X) < 0.34 pb and M$$\tilde{χ}$$±1} > 81.5 GeV/c2 for tan β = 2, μ = -600 GeV/c2$$\tilde{q}$$ = M$$\tilde{g}$$. We also present limits on a SU(5) x U(1) supergravity model and a 4 and 1/2 parameter Minimal SUGRA model.
