Title: Search for long-lived parents of Z{sup 0} bosons in p{bar p} collisions at {radical} (s) =1.8thinspTeV

We search for new long-lived particles which decay to Z{sup 0} bosons by looking for Z{sup 0}{r_arrow}e{sup +}e{sup {minus}} decays with displaced vertices. We find no evidence for parent particles of the Z{sup 0} with long lifetimes in 90thinsppb{sup {minus}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{sup 0} parent and a fourth-generation, charge {minus} (1) /(3) quark that decays into Z{sup 0}b. {copyright} {ital 1998} {ital The American Physical Society}
