Looking for extra neutral gauge boson effects in longitudinally polarized e{sup +}e{sup -} {yields} W{sup +}W{sup -}

Abstract

We study indirect manifestations of a heavy E{sub 6} Z` in the process e{sup +}e{sup -} {yields} W{sup +}W{sup -} with longitudinally polarized e{sup {+-}} beams at energies typical of planned next-generation colliders, such as the NLC({radical}s{>=}500 GeV). We find the kinematical regions where these effects can be expected to be most pronounced, and then we assess the sensitivity of cross sections to the Z - Z` mixing angles or alternatively to the Z` mass. It results that the limits on the mixing angle could be improved to a few x 10{sup -4}, or equivalently those for the Z` mass to {approx} 10 - 20 TeV. (author). 24 refs, 6 figs.
