We report on a search for supersymmetry using the DØ detector. The 1994–1996 data sample of √s=1.8 TeV p¯p collisions was analyzed for events containing two leptons (e or μ), two or more jets, and missing transverse energy. Assuming the minimal supergravity model, with A0=0 and μ<0, various thresholds were employed to optimize the search. No events were found beyond expectation from the background. We set a lower limit at the 95% C.L. of 255 GeV/c2 for equal mass squarks and gluinos for tanβ=2, and present exclusion contours in the (m0,m1/2) plane for tanβ=2–6.Received 9 February 2000DOI:https://doi.org/10.1103/PhysRevD.63.091102©2001 American Physical Society
