Abstract

We search for new long-lived particles which decay to Z0 bosons by looking for Z0→e+e- decays with displaced vertices. We find no evidence for parent particles pf the Z0 with long lifetimes in 90 pb-1 of data from the CDF experiment at Fermilab. We set a cross section limit as a function of the lifetime of the parent particle for both a generic Z0 parent and a fourth-generation, charge -1/3 quark that decays into Z0b.
