Abstract
Expectations for constraints on extra Z bosons are derived for LEP2 and future linear e+e− colliders For typical GUTs a Z′ with MZ′ ≤ 3 to 6sqrt s may cause observable effects The Z′ discovery limits are dominated by statistical errors However if a Z′ signal is observed the discrimination between different models becomes much worse if systematic errors are taken into account Discrimination between models is possible for M Z⌕ime 3sqrt s A determination of Z′ff couplings independently of models becomes attractive with future colliders Anticipated bounds are determined
