Model Independent $Z^{'}$ Constraints at Future $e^{+} e^{-}$ Colliders}

Abstract

Model independent constraints on the mass of extra neutral gauge bosons and their couplings to charged leptons are given for LEP~II and a 500\,GeV $e^{+} e^{-}$ collider. Analytical exclusion limits are derived in the Born approximation. The $Z^{'}$ limits obtained with radiative corrections are always worse than those calculated at the Born level. Polarized beams are only useful for degrees of polarization essentially larger than 50\%. Known discovery limits on extra $Z$ bosons predicted by popular $Z^{'}$ models are reproduced as special cases. The $Z^{'}$ constraints are compared to those predicted by four fermion contact interactions.
