Search for R-Parity Violating Supersymmetry Using Like-Sign Dielectrons in pp¯ Collisions at √s = 1.8 TeV

We present a search for like-sign dielectron plus multijet events using 107 pb^-1 of data in pp¯ collisions at s = 1.8 TeV collected in 1992-1995 by the CDF experiment. Finding no events that pass our selection, we set σ×BR limits on two supersymmetric processes that can produce this experimental signature: gluino-gluino or squark-antisquark production with R-parity violating decays of the charm squark or lightest neutralino via a nonzero λ'₁₂₁ coupling. We compare our results to the next-to-leading order calculations for gluino and squark production cross sections and set lower limits on M\(g~\), M\(t~₁\), and M\(q~\).
