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]) .
