We study the reactions $e^{\mathrm{-}}$$e^{+}$→νν¯ZZ and $e^{\mathrm{-}}$$e^{+}$→$e^{\mathrm{-}}$$e^{+}$ZZ using exact matrix elements. In particular, we examine the cross section for the production of a standard-model Higgs boson at several machine energies. In addition, we study the behavior of the vector-boson scattering processes when the Higgs-boson mass is infinite, focusing on the percentage of longitudinally polarized Z’s as a signature.
