Abe, F.

We present a search for like-sign dielectron plus multijet events using 107 pb-1 of data in \ppbar collisions at $$\sqrt{s} = 1.8$$ TeV collected in 1992-95 by the CDF experiment. Finding no events that pass our selection, we set $$\sigma\cdot Br$$ limits on two SUSY 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 non-zero lambda'_121 coupling. We compare our results to NLO calculations for gluino and squark production cross sections and set lower limits on M(gluino), M(stop1), and M(squark).
