| Summary: | Supersymmetric gluons (gluinos, []) and supersymmetric quarks (squarks, []) will be pair-produced in p[] collisions at []= 1.8 TeV at the Fermilab Tevatron if kinematically accessible. Gluinos and squares can decay via chartings and neutralinos to final states containing two or more leptons. Since the gluino is a Majorana particle, a large fraction of like-sign dilepton events will be observed. This property effectively reduces the Standard Model processes which largely yield opposite-sign dilepton events. Thus, the strategy of this analysis is to search for an excess of events containing two isolated leptons with same-sign charge, missing energy, and jets. Based on 106 pb[] of data, we observe zero events and have set a 95 % confidence level limit for the gluino mass. |
