abstract

  • We report on a search for supersymmetric squark and gluino particles in a data sample of 19 [Formula presented] of [Formula presented] collisions at [Formula presented] TeV recorded by the Collider Detector at Fermilab. We searched for events containing jets plus appreciable missing transverse energy [Formula presented] This signature is indicative of pair production and subsequent decay of squarks and/or gluinos. After all cuts, there are [Formula presented] events with [Formula presented] GeV and three jets, and [Formula presented] events with [Formula presented] 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 [Formula presented] confidence level, we find gluino and squark mass limits up to 216 [Formula presented] assuming equal gluino and squark masses, and gluino mass limits up to [Formula presented] [Formula presented] independent of squark mass. © 1997 The American Physical Society.
