Title: Search for R -Parity Violating Supersymmetry Using Like-Sign Dielectrons in p{ovr p} Collisions at {radical} (s) =1.8 TeV

Abstract

We present a search for like-sign dielectron plus multijet events using 107 pb{sup {minus}1} of data in p{ovr p} collisions at {radical} (s) =1.8 TeV collected in 1992{endash}1995 by the CDF experiment. Finding no events that pass our selection, we set {sigma}{times}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 {lambda}{sup {prime}}{sub 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({tilde g}) , M({tilde t}{sub 1}) , and M({tilde q}) . {copyright} {ital 1999} {ital The American Physical Society}
