Abstract
The possible existence of a new heavy quark Q that decays predominantly viathe flavor changing neutral current transition Q→qZ is discussed. Candidates include a fourth generation charge - 1 3 quark, or a more exotic vector-like quark. Such particles are interesting both as extensions of the standard model and due to their unique decay modes. The primary experimental indication of the pair production and subsequent decay of such quarks is ZZ pair production at an essentially strong interaction rate. This mode can then constitute an unexpected background to the searches for other particles. In particular the channel QQ→ZZ+X can generate a serious background to the search for the Higgs boson via the H0→ZZ mode at the SSC. Thus it is essential to search for such new heavy quarks at the Tevatron. Possible detection signatures for this purpose are discussed. © 1991.
