Title: Search for Long-lived Charged Massive Particles at CDF

Abstract: A search for long-lived charged massive particles in CDF's Run1bdata sample is presented. The search looks for highly ionizingtracks which would result from slowly moving massive particles.We search for strongly produced particles using a stable color triplet quark as a reference model, and a separate search wasperformed for weakly produced particles using long-livedsleptons in Gauge Mediated Supersymmetry Breaking as a referencemodel. No excess over background was observed, and we derivelimits on the cross-sections for production of these particles.Prospects for RunII are also discussed.
