Abstract: (APS)

We report on a search for supersymmetry using dilepton events which complements the classic missing ET plus multijet analyses. Using 19pb−1 of pp¯ collisions at s=1.8TeV recorded with the Collider Detector at Fermilab we have searched for squarks and gluinos decaying into charginos and producing events with two leptons. We observe one candidate event. In comparison, the expected number of background events from standard model processes is 2.39±0.63(stat)−0.42+0.77(syst). Hence we set limits on gluino and squark production based on predictions from the supergravity inspired minimal supersymmetric extension of the standard model.
