2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/44961We present recent developments in the diagnostic study of heavy gauge bosons at future colliders with the emphasis on the determination of gauge couplings of $Z'$ to quarks and leptons. Proposed diagnostic probes at future hadron colliders are discussed. The study of statistical uncertainties expected for the above probes at the LHC and $M_{Z'}\simeq 1$ TeV shows that three out of four normalized couplings can be determined, thus allowing for a distinction between models. The complementary nature of the probes at future $e^+e^-$ colliders is also discussed.(based on talks presented by M.C. at Workshop on Linear e+e- Colliders, Waikoloa, Hawaii April, 1993, and International Europhysics Conf. on High Energy Physics, Marseilles, July, 1993), 9 pages (+1 figure available on request), UPR-584-THigh Energy Physics - Phenomenologytext
