| dc.description | We report on a search for supersymmetry using the DØdetector. The 1994-1996 data sample of $\sqrt{s}=1.8$ TeV $p\bar{p}$ 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 $A_0=0$ and $μ<0$, various thresholds were employed to optimize the search. No events were found beyond expectation from background. We set a lower limit at the 95% C.L. of 255 GeV/$c^2$ for equal mass squarks and gluinos for $\tanβ=2$, and present exclusion contours in the $(m_0,m_{1/2})$ plane for $\tanβ=2$--6. | |
