Abstract
We present a search for like-sign dielectron plus multijet events using 107pb− 1 of data in pp collisons 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(∼ t1) and M(∼ q). © 1999 The American Physical Society.
