We examine the scenario where a leptophobic Z' boson accounts for the excessof events in the Wjj channel as observed by CDF. We assume generationindependent couplings for the Z' and obtain allowed regions for the fourhadronic couplings using the cross section range quoted by CDF as well asconstraints from dijet production at UA2. These coupling regions translate intowell-determined rates for the associated production of Z/\gamma+Z' at theTevatron and LHC, as well as W+Z' at the LHC,that are directly correlated withthe Wjj rate observed at the Tevatron. The Wjj rate at the LHC is large andthis channel should be observed soon once the SM backgrounds are under control.The rates for Z/\gamma+Z' associated production are smaller, and theseprocesses should not yet have been observed at the Tevatron given the expectedSM backgrounds. In addition, we also show that valuable coupling information isobtainable from the distributions of other kinematic variables, e.g., M_{WZ'},p_T^W, and \cos \theta_W^*. Once detected, these associated productionprocesses and the corresponding kinematic distributions examined here willprovide further valuable information on the Z' boson couplings.
