Abstract The general expression for the differential cross section of the reactione + e −→γ,Z 1 0 ,Z 2 0 , ..., →e + e − with an arbitrary initial polarization state is derived in the context of electroweak gauge models with more than one neutral boson. Angular distributions, azimuthal asymmetries in the case of natural polarization, and longitudinal polarization asymmetries for models of the typeSU(2)×U(1)×G (G=Ũ(1),SŨ(2)) and left-right symmetric models are compared with the standard model results. For the angular distributions withe ± having equal helicities a∼10% deviation from the standard model is predicted already below 50 GeV for models of the first type withZ 1 0 masses up to 80 GeV. At energies around the firstZ 1 0 a study of azimuthal and polarization asymmetries yields the possibility of distinguishing between different models.
