Limits on the masses of supersymmetric particles from 1.8-TeV pp̅ collisions

An analysis of pp̅ collision events at √ s =1.8 TeV with jets and large missing transverse energy finds no event with missing transverse energy &gt;40 GeV. This result yields a 90%-C.L. limit on the cross section for one-jet-event production of &lt;0.1 nb for events with the jet in the pseudorapidity range ||η ||&lt;1.0 and with jet E<SUB>T</SUB>&gt;52 GeV. Limits on the masses of squarks and gluinos in a minimal supersymmetry model are also set. At the 90% C.L., m<SUB>q</SUB>~&gt;74 GeV and m<SUB>g</SUB>~&gt;73 GeV
