Search for squarks and gluinos in pp̅ collisions at √s = 1.8TeV

Abstract

We present a search for events consistent with the production and decay of the squarks and gluinos of the minimal supersymmetric standard model (MSSM) in the D0 detector at the Fermilab Tevatron pp̅ collider. We examined data for events containing large missing transverse energy and three or more jets. We observed no excess of events above the expected yield from standard model processes. For a choice of MSSM parameter values, we set a lower limit at the 95% confidence level on the mass of the gluino of 144 GeV /c² for all squark masses and a lower limit of 212 GeV /c² for equal squark and gluino masses.
