摘要

We present results of the first search for like-sign dilepton (e±e±, e±μ±, μ±μ±) events associated with multijets and large missing energy using 106pb−1 of data in pp¯ collisions at √s = 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) and squarks (q) in a constrained framework of the minimal supersymmetric standard model. At tan β = 2 and μ = −800 GeV/c2, we set 95% confidence level limits of Mg > 221 GeV/c2 for Mg ≃ Mq, and Mg > 168 GeV/c2 for Mq ≫ Mg, both with small variation as a function of μ.
