Abstract
We report on a search for R-parity-violating supersymmetry in p (p) over bar collisions at root s = 1.8 TeV using the DO detector at Fermilab. Events with at least two electrons and four or more jets were studied. We observe two events in 99 +/- 4.4 pb(-1) of data, consistent with the expected background of 1.8 +/- 0.4 events. This result is interpreted within the framework of minimal low-energy supergravity supersymmetry models. Squarks with mass below 243 GeV/c(2) and gluinos with mass below 227 GeV/c(2) are excluded at the 95% C.L. for A(0) = 0, mu < 0, tan beta = 2, and a finite value for any one of the six R-parity-violating couplings lambda(1jk)' (j = 1, 2 and k = 1, 2, 3).
