Identifying the origin of new gauge bosons at the Superconducting Super Collider

We examine the ability of the detector of the Solenoidal Detector Collaboration (SDC) to identify the origin of a new neutral gauge boson $Z_2$ in the TeV mass range at the Superconducting Super Collider. Specifically, given the measurements of the $Z_2$ production cross section, width, and leptonic forward-backward asymmetry, together with their associated statistical and systematic errors, we address two related questions: (i) For two differnet extended electroweak models, up to what mass can their corresponding $Z_2$ bosons be distinguished, and (ii) how well can the $Z_2$ couplings be determined? Our calculations include $O\left({\alpha }_s^2\right)$ QCD, as well as oblique electroweak radiative corrections to the above quantities, and allow for uncertainties due to structure functions, detector efficiencies, lepton identification, luminosity measurement errors, and finite lepton-pair mass resolution, using the specifications of the SDC detector. Nine distinct classes of extended electroweak models are investigated and results are obtained for integrated luminosities of ${10}^4$ and ${10}^5$ ${\mathrm{pb}}^{-1\mathrm{}}$.
