Search for gluinos and squarks at the Fermilab Tevatron collider

We report on a search for supersymmetric squark and gluino particles in a data sample of 19 pb^-1 of pp̄ collisions at √s=1.8 TeV recorded by the Collider Detector at Fermilab. We searched for events containing jets plus appreciable missing transverse energy (/ET). This signature is indicative of pair production and subsequent decay of squarks and/or gluinos. After all cuts, there are $18$ events with /ET>60 GeV and three jets, and $6$ events with /ET>60 GeV and four jets. These numbers of events are consistent with estimates of standard model processes plus detector-induced background sources. The analysis yields lower limits on gluino and squark masses, based on the predictions from the mnimal supersymmetric extension of the standard model. At the $95%$ confidence level, we find gluino and squark mass limits up to 216 GeV/c², assuming equal gluino and squark masses, and gluino mass limits up to $173$ GeV/c², independent of squark mass.
