Abstract
We perform a comprehensive analysis of the polarization effects on the e(+) e(-) --> W+W- process in the presence of an extra neutral gauge boson at th e future e(+)e(-) linear collider energies. The sensitivity for probing the Z-Z' mixing is substantially enhanced when the polarizations of the produc ed W bosons and the incident beams are considered. We find that the chi-mod el and the left-right model get stricter constraints from the cross section for both longitudinally polarized W bosons while the psi-model and the eta -model get stricter bounds from the beam polarization asymmetry.
