Abstract
We have searched in p (p) over bar collisions at root s = 1.8 TeV for events with three charged leptons and missing transverse energy. In th e minimal supersymmetric standard model, we expect trilepton events fr om chargino-neutralino (<(chi)over tilde>(+/-)(1)<(chi)over tilde>(0)( 2) pair production, with subsequent decay into leptons. We observe no candidate e(+)e(-)e(+/-), e(+)e(-)mu(+/-), e(+/-)mu(+)mu(-), or mu(+)m u(-)mu(+/-) events in 106 pb(-1) integrated luminosity. We present lim its on the sum of the branching ratios times cross section for the fou r channels: sigma(<(chi)over tilde>1)(+/-)(<(chi)over tilde>2)B-0(<(ch i)over tilde>(+/-)(1)<(chi)over tilde>(0)(2) --> 3l + X) < 0.34 pb, M( <(chi)over tilde>1)(+/-) > 81.5 GeV/c(2), and M(<(chi)over tilde>2)(0) > 82.2 GeV/c(2) for tan beta = 2, mu = -600 GeV/c(2), and M-(q over t ilde) = M-(g over tilde).
