Abstract

We report on a search for R-parity-violating supersymmetry in pp̅ collisions at √s=1.8TeV using the DØ detector at Fermilab. Events with at least two electrons and four or more jets were studied. We observe two events in 99±4.4pb-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 243GeV/c2 and gluinos with mass below 227GeV/c2 are excluded at the 95% C.L. for A0=0, µ<0, tanβ=2, and a finite value for any one of the six R-parity-violating couplings λ1jk'(j=1, 2 and k=1, 2, 3).
