We present the results of two searches for new particles that couple Z bosons in pp collisions at s = 1.96 TeV using the Collider Detector at Fermilab (CDF). In the first, we search for a long-lived parent of the Z boson using a data sample with a luminosity of 163 pb-1. Finding no significant excess above background, we set a limit on a fourth generation model as a function of mass and lifetime. In the second, we search for a particle that decays to a Z boson in conjunction with jets using a data sample with a luminosity of 1.06 fb-1. Finding no significant excess above background, we set a limit on a fourth generation model as a function of mass.
