Abstract

We search for new long-lived particles which decay to

Z^{0}

bosons by looking for

Z^{0} \to e^{+} e^{-}

decays with displaced vertices. We find no evidence for parent particles of the

Z^{0}

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^{0}

parent and a fourth-generation, charge

- \frac{1}{3}

quark that decays into

Z^{0} b .
