Abstract

The light gaugino scenario predicts that the lighter chargino mass is less than mW, gluino and lightest neutralino masses are <~ 1 GeV, and the dominant decay mode of charginos and non-LSP neutralinos is generically to three jets. The excess &#34;4j&#34; events observed by ALEPH in e+ e- annihilation at 133 GeV may be evidence that m(C1) = 53 GeV. If so, m(N2) = 110-121 GeV, m(N2) = 38-63 GeV, m(N3) = 75-68 GeV; m(sneue) is probably ~m(C1). A detailed analysis of the multi-jet events is needed to exclude this possibility. Consequences for FNAL and higher energy LEP running are given.
