We present results of the first search for like-sign dilepton (e(+/-)e(+/-),e(+/-)mu (+/-),mu (+/-)mu (+/-)) events associated with multijets and large missing energy using 106 pb(-1) of data in p (p) over bar collisions at roots = 1.8 TeV collected during 1992-1995 by the CDF experiment. Finding no events that pass our selection, we examine pair production of gluinos ((g) over tilde) and squarks; ((q) over tilde) in a constrained framework of the minimal supersymmetric standard model. At tan beta = 2 and mu = -800 GeV/c(2), we set 95% confidence level limits of M-(g) over tilde > 221 GeV/c(2) for M-(g) over tilde similar or equal to M-(q) over tilde, and M-(g) over tilde > 168 GeV/c(2) for M-(q) over tilde >> M-(g) over tilde, both with small variation as a function of mu.

Abstract

We present results of the first search for like-sign dilepton (e(+/-)e(+/-),e(+/-)mu (+/-),mu (+/-)mu (+/-)) events associated with multijets and large missing energy using 106 pb(-1) of data in p (p) over bar collisions at roots = 1.8 TeV collected during 1992-1995 by the CDF experiment. Finding no events that pass our selection, we examine pair production of gluinos ((g) over tilde) and squarks; ((q) over tilde) in a constrained framework of the minimal supersymmetric standard model. At tan beta = 2 and mu = -800 GeV/c(2), we set 95% confidence level limits of M-(g) over tilde > 221 GeV/c(2) for M-(g) over tilde similar or equal to M-(q) over tilde, and M-(g) over tilde > 168 GeV/c(2) for M-(q) over tilde >> M-(g) over tilde, both with small variation as a function of mu.
