A leptophobic massive vector boson at the Tevatron and the LHC
  Recent measurements of the single inclusive jet cross section at the Tevatron by the CDF Collaboration maybe suggest a modified picture of QCD in the large $E_T$ range. One possible explanation of the measured jet excess is the introduction of a neutral heavy vector boson $Z'$. A parameter fit of this new model to the CDF data, in leading order perturbation theory, is performed, and the question of how the corresponding single inclusive jet cross sections and the dijet angular distributions at the LHC are affected by this additional $Z'$ is discussed. We conclude that the $Z'$ will play a pivotal role for typical LHC centre-of-mass energies, thus providing a direct test of this theory.
