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 ${\mathrm{pb}}^{\mathrm{-}1}$ of $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{}$ TeV recorded by the Collider Detector at Fermilab. We searched for events containing jets plus appreciable missing transverse energy $\left({\stackrel{/}{E}}_T\right).\mathrm{}$ This signature is indicative of pair production and subsequent decay of squarks and/or gluinos. After all cuts, there are $18$ events with ${\stackrel{/}{E}}_T>60\mathrm{}$ GeV and three jets, and $6$ events with ${\stackrel{/}{E}}_T>60\mathrm{}$ 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 $\mathrm{G}\mathrm{e}\mathrm{V}/c^2,$ assuming equal gluino and squark masses, and gluino mass limits up to $173$ $\mathrm{G}\mathrm{e}\mathrm{V}/c^2,$ independent of squark mass.
