摘要
An analysis by the ATLAS Collaboration has recently shown, contrary to popular belief, that a combination of strategic cuts, excellent mass resolution, and detailed knowledge of the QCD backgrounds from direct measurements can be used to extract a signal in the Z'-->jj channel for certain classes of extended electroweak models. We explore the possibility that the data extracted from Z dijet peak will have sufficient statistical power as to supply information on the couplings of the Z' provided it is used in conjunction with complementary results from the Z'-->l+l- ''discovery'' channel. We show, for a 1 TeV Z' produced at the SSC, that this technique can provide a powerful new tool with which to identify the origin of Z'. Extensions of this analysis to the CERN LHC as well as for a more massive Z' are discussed.
