Abstract

We discuss the theory and phenomenology of decays of a leptophobic U(1) x gauge boson X, such as has been proposed to explain the alleged deviations of R b and R c from standard model predictions. If the scalars involved in the breaking of the SU(2) × U(1) symmetry are sufficiently light, X will sometimes decay into a charged (or neutral) scalar along with an oppositely-charged W (or Z). These decay modes could yield clean signals for the leptophobic gauge bosons at hadron colliders and provide an interesting window into the Higgs sector of the theory.
