Prominent decay modes of a leptophobic Z'

An anomaly-free U(1) charge Q' has recently been identified within the group E_6 for which the familiar leptons (the left- and right-handed electron and the left-handed neutrino) have Q' = 0. It is pointed out that the Q' charges of several {\it exotic} leptons within E_6 matter multiplets are quite large, leading to the prediction that half of the decays of the so-called ``leptophobic'' Z' bosons coupling to Q' are to these exotic leptons. Other large Q' charges include those of standard up-type quarks and exotic down-type quarks. Substantial forward-backward asymmetries are expected in u \bar u \to Z' \to f \bar f channels when f is a standard up-type quark, an exotic down-type quark, or an exotic lepton.
