Discovery and Identification of Extra Gauge Bosons

Abstract

The discovery potential and diagnostic abilities of proposed future colliders for new heavy neutral ($Z^{\prime }$) and charged ($W^{\prime }$) gauge bosons are summarized. Typical bounds achievable on $M_{Z^{\prime },W^{\prime }}$ at the TEVATRON, DI-TEVATRON, LHC, 500 GeV NLC, and 1 TeV NLC are $\sim$1~TeV, $\sim$2~TeV, $\sim$4~TeV, 1--3~TeV, and 2--6~TeV, respectively. For $M_{Z^{\prime }}\sim$1 TeV the LHC will have the capability to determine the magnitude of normalized $Z^{\prime }$ quark and lepton couplings to around $10-20\%$, while the NLC would allow for determination of the couplings (including their signs) with a factor of 2 larger error-bars, provided heavy flavor tagging and longitudinal polarization of the electron beam is available.
