摘要：

We reexamine the unitarity constraints on the high-energy scattering of longitudinal W s and Zs and Higgs bosons in the standard model including one-loop corrections, and make an Argand-diagram analysis of the j=0 scattering amplitudes. We find that the theory is approximately unitary and weakly interacting at O(2) for Higgs-boson couplings <c=1.52 (equivalent to MH<350400 GeV), but that O(3) or higher corrections must be included to restore perturbative unitarity for larger values of or MH. © 1990 The American Physical Society.
