Abstract: Data from proton‐antiproton collisions at center‐of‐mass energy of 1.8 TeV are searched for evidence of SUSY particles. One analysis looks for the three‐lepton final state from chargino‐neutralino production. No events are observed. Another analysis looks for three or more jets and large missing energy as a signal of squark or gluino pair production. No significant excess of data above background is observed. The results of these searches are to extend limits on SUSY models beyond previous limits within a restricted parameter space of the models.
