We present a search for like-sign dielectron plus multijet events using 107 pb(-1) of data in p (p) over bar collisions at root s = 1.8 TeV collected in 1992-1995 by the CDF experiment.

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) over tilde), M((t) over tilde(1)), and M((q) over tilde).

Abstract

We present a search for like-sign dielectron plus multijet events using 107 pb(-1) of data in p (p) over bar collisions at root s = 1.8 TeV collected in 1992-1995 by the CDF experiment. Finding no events that pass our selection, we set sigma x 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'(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) over tilde), M((t) over tilde(1)), and M((q) over tilde).
