摘要
We report on a search for supersymmetry using the D empty set detector. The 1994-1996 data sample of roots = 1.8 TeV p (p) over bar collisions was analyzed for events containing two leptons (e or mu), two or more jets, and missing transverse energy. Assuming the minimal supergravity model, with A(0) = 0 and mu = 2, and present exclusion contours in the (m(0),m(1/2)) plane for tan beta = 2-6.
