Abstract:
We have searched in collisions at = 1.8 TeV for events with three charged leptons and missing transverse energy. In the Minimal Supersymmetric Standard Model, we expect trilepton events from chargino-neutralino (\chione \chitwo) pair production, with subsequent decay into leptons. We observe no candidate , , or events in 106 pb integrated luminosity. We present limits on the sum of the branching ratios times cross section for the four channels: \sigma_{\chione\chitwo}\cdot BR(\chione\chitwo\to 3\ell+X) < 0.34~pb, M_\chione > 81.5 \mgev\sp and M_\chitwo > 82.2 \mgev\sp for , ~\mgev\sp and M_\squark= M_\gluino.Note:
