Search for Gluinos and Scalar Quarks in $p\bar{p}$ Collisions at $\sqrt{s}=1.8$ TeV using the Missing Energy plus Multijets Signature

We have performed a search for gluinos ($\gls$) and squarks ($\sq$) in a data sample of 84 pb$^{-1}$ of \ppb collisions at $\sqrt{s}$ = 1.8 TeV, recorded by the Collider Detector at Fermilab, by investigating the final state of large missing transverse energy and 3 or more jets, a characteristic signature in R-parity-conserving supersymmetric models. The analysis has been performed `blind', in that the inspection of the signal region is made only after the predictions from Standard Model backgrounds have been calculated. Comparing the data with predictions of constrained supersymmetric models, we exclude gluino masses below 195 \gev (95% C.L.), independent of the squark mass. For the case $\msq \approx \mgls$, gluino masses below 300 \gev are excluded.
