Search for R-Parity Violating Supersymmetry in the Dielectron Channel

We report on a search for R-parity-violating supersymmetry in pp? collisions at ?s = 1.8TeV using the D0 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, ?<0, tan? = 2, and a finite value for any one of the six R-parity-violating couplings ?1jk? ( j = 1, 2 and k = 1, 2, 3).
