Abstract: The production of new spin-1 chiral bosons at the hadron colliders, theFermilab Tevatron and the CERN LHC, is considered. The masses of the chiralbosons can be determined on the basis of experimental data of preciselow-energy experiments, which already indicate indirectly their existence. Theycan explain, for example, the serious 4.5 sigma discrepancy between themeasured and the predicted two pion branching ratio of the tau decay and thesign of the 3.3 sigma deviation of the muon (g-2) theoretical prediction fromthe experimental value. Quantitative evaluations of the various differentialcross-sections of the chiral boson production at hadron colliders are madeusing the CalcHEP package. It is noteworthy that the Tevatron data already hintthe existence of the lightest charged chiral boson with a mass around 500 GeV.New Tevatron data and the LHC results will definitely confirm or reject thisindication. In the positive case the LHC would be able to discover allpredicted charged and neutral chiral bosons spanning in mass up to 1 TeV.
