We search for new long-lived particles which decay to Z(o) bosons by looking for Z(o)-->e(+)e(-) decays with displaced vertices. We find no evidence for parent particles of the Z(o) 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 Z(o) parent and a fourth-generation, charge -1/3 quark that decays into Z(o)b.

Abstract
We search for new long-lived particles which decay to Z(o) bosons by looking for Z(o)-->e(+)e(-) decays with displaced vertices. We find no evidence for parent particles of the Z(o) 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 Z(o) parent and a fourth-generation, charge -1/3 quark that decays into Z(o)b.
