Phenomenology of Charginos and Neutralinos in the Light Gaugino Scenario
Glennys R. Farrar
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 "4j" 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.
